Editor’s Note

The chemical industry is the cornerstone of modern industry, often referred to as the “industry of industries.” Under the combined influence of geopolitical tensions and a global restructuring of production capacity, the competitive landscape of the global chemical market is undergoing profound adjustments. Recently, U.S.-based Chemical & Engineering News released its 2026 list of the Top 50 Global Chemical Companies, with 11 Chinese firms making the cut—placing China first worldwide in terms of the number of entrants. At the concurrently held 2026 Economic Outlook Conference for the Petroleum and Chemical Industries, the latest data revealed that in the first half of this year, China’s chemical sector generated 5 trillion yuan in operating revenue, up 9.7% year over year, and posted profits of 312.63 billion yuan, a 65.2% increase compared with the same period last year. Against the backdrop of weakening global demand and escalating geopolitical risks, these deep-seated shifts in the chemical industry underscore an era marked by the sector’s iterative evolution and the dawn of a new chapter. This special issue systematically traces the development trajectory of the global chemical industry, examines the scale and profitability differentiations among major chemical companies, and offers valuable insights for decoding the current structure and emerging trends of the global chemical market.

2026 Global Top 50 Chemical Companies Ranking

Founded in 1923, the American Chemical Society’s (ACS) magazine Chemical & Engineering News (C&EN) has, since the early 2000s, annually published a list of the world’s top 50 chemical companies, ranked by their previous year’s chemical‑sales revenue. This ranking is widely regarded as the most authoritative in the global chemical industry. The latest 2026 list shows that China has 11 companies on the roster; aside from the two state‑owned enterprises, Sinopec and PetroChina, the remaining nine are private firms, reflecting a vibrant landscape in which enterprises of diverse ownership structures are advancing in tandem and pursuing shared growth.

However, data from Chemical & Engineering News also show that the global chemical industry is currently experiencing its most severe downturn in decades, with the duration and severity of this impact exceeding those of most previous cycles. The 50 companies on the list reported combined chemical‑sales revenues of $965.8 billion in 2025, down 5.8% from the previous year, with sales declining at 39 of them. Among the 37 firms that disclosed operating profits, total operating profit from chemical operations totaled $47.2 billion, a 19.5% drop from the prior year; operating profits fell at 25 companies, while 7 reported losses.

According to a 2025 ranking published by Chemical & Engineering News, the top 50 global chemical companies reported sales revenues that were virtually unchanged from the previous year, while profits grew by 8.1%. Amid market pressures, these companies have tightened their 2025 budgets. Specifically, 32 firms allocated a combined $67.7 billion in capital expenditures, down 7.8% year over year, signaling a deliberate reduction in new‑capacity investments—one of the key factors contributing to the industry’s downturn. Meanwhile, R&D spending across 29 companies totaled $12.2 billion, a 2.4% decline compared with the prior year.

The global chemical industry is broadly sluggish, primarily due to overcapacity. Among the top ten companies, Sinopec, PetroChina, Saudi Basic Industries Corporation, and LyondellBasell all reported declines in chemical sales revenue by 2025. Moreover, diversified chemical firms such as BASF and Dow Chemical also saw a drop in sales, largely attributable to weak performance in their chemical businesses.

Industry forecasts suggest that the chemical market will gradually recover around 2030. Chemical companies have already responded to adverse conditions by cutting capacity; for instance, ExxonMobil and Saudi Basic Industries Corporation have shut down their ethylene cracker facilities in Europe due to the region’s economic downturn. Meanwhile, Japanese and South Korean chemical firms are advancing business restructuring. In China, policy measures will also be employed to guide the rapid expansion of domestic chemical enterprises in recent years, encouraging the orderly phase-out of outdated production capacity to curb excessive competition.

In 2025, the global chemical industry’s performance will be driven by specialty chemicals and industrial gases companies. Among them, specialty chemicals firms such as Arkema and Ecolab reported only modest declines in sales, while the industrial gases giant Linde Group even posted a slight increase in revenue.

In 2025, the global fertilizer industry gradually rebounded, with companies such as Yara, Mosaic, Nutrien, and OCP all reporting substantial increases in sales revenue. Notably, Morocco’s phosphate producer OCP, driven by a sharp surge in sales, entered the Global Top 50 Chemical Companies for the first time.

In 2026, the outlook for global chemical companies remains uncertain. The Middle East conflict and the resulting disruptions to shipping through the Strait of Hormuz have upended analysts’ earlier forecasts. Chemical production in the Middle East has nearly ground to a halt, while Asia has seen output slow due to shortages of Middle Eastern crude oil and naphtha feedstocks. Meanwhile, regions less directly affected—such as Europe and North America—are experiencing a temporary uptick in market activity. Even if the Middle East crisis eases soon, it will still take considerable time for global chemical supply chains to fully recover.

Overview of Major Global Chemical Companies

1. BASF

BASF SE, a German chemical company founded in 1865, entered the Chinese market as early as the beginning of the 20th century, introducing vat dyes. In 1989, BASF and Gaoqiao Petrochemical established China’s first joint venture, Shanghai Gaoqiao BASF Dispersions Co., Ltd., and have since steadily deepened their presence in the Chinese market. In 2005, the integrated production base of Yangzi Petrochemical–BASF Co., Ltd., a Sino‑German joint venture set up in Nanjing, officially commenced operations, marking at the time the largest Sino‑German petrochemical joint venture project.

For many years, BASF has consistently ranked highly in various industry‑leading rankings, including inclusion in the Fortune Global 500, the BrandZ Top 100 Most Valuable Global Brands, and the Hurun China Top 200 Foreign‑Invested Enterprises. In Chemical & Engineering News’ 2026 list of the World’s Top 50 Chemical Companies, BASF topped the ranking with chemical sales revenue of US$67.447 billion in 2025.

BASF has topped the Global Top 50 Chemical Companies ranking for seven consecutive years, but its leading position is now under pressure from industry challenges. Last October, BASF sold a majority stake in its automotive coatings business to Carlyle Group and the Qatar Investment Authority for $8.9 billion; this segment generated $4.2 billion in sales revenue in 2025. Meanwhile, BASF has announced that it will spin off its agrochemicals and surfactants businesses as separate non-core units, with the former generating approximately $10.8 billion in annual sales and the latter about $10.1 billion.

Driven by strong performance in its catalysts business, BASF announced last October that it would continue to retain this segment. Furthermore, having reduced the cost of battery materials through technological advancements, BASF may remain committed to this line of business. In January of this year, the ethylene complex at BASF’s integrated site in Zhanjiang was successfully commissioned, underscoring the company’s steady and prudent approach to operations in China.

2. Sinopec

Its full name is China Petrochemical Corporation, and it is China’s largest supplier of refined oil and petrochemical products. It is also a super-large integrated energy and chemical group that seamlessly links upstream and downstream operations, production, supply, and sales, as well as domestic and international trade. Currently, the company is accelerating its transformation into a comprehensive energy service provider spanning oil, gas, hydrogen, electricity, and related services, striving to become a world‑leading, modern energy and chemical enterprise.

In the Global Top 50 Chemical Companies ranking, Sinopec has consistently held second place worldwide since 2020. In the latest 2026 list, Sinopec ranked second with chemical sales revenue of US$52.598 billion.

4. ExxonMobil

ExxonMobil ranked fourth on the Global Top 50 Chemical Companies list, with chemical sales of $39.98 billion in 2025, trailing only Sinopec and PetroChina; it also surpassed Dow Chemical to become the largest chemical company in the United States. Compared with the previous year’s ranking, ExxonMobil moved up one spot.

However, ExxonMobil’s recent strategic focus has been on scaling back its operations. Affected by the prolonged downturn in the European chemical market, the company has progressively shut down several chemical facilities across Europe, including a steam cracker in France and an ethylene plant in Scotland. Furthermore, in light of proposed EU regulations, ExxonMobil has also suspended plans to build two plastic‑recycling plants in Belgium and the Netherlands. At the same time, the company is pursuing a retrenchment strategy domestically in the United States, putting on hold its $8.6 billion petrochemical complex project in Texas and pausing progress on low‑carbon hydrogen initiatives.

5. Dow Chemical

Dow Chemical is a materials‑focused chemical company founded in 1897 and headquartered in Michigan, USA. In 2019, it became an independent entity listed on the New York Stock Exchange. With operations spanning the globe and manufacturing facilities in 29 countries and regions, Dow reported chemical sales of US$39.968 billion in 2025, ranking fifth among the world’s top 50 chemical companies.

Dow operates three major business segments—Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure, and Performance Materials & Coatings—providing materials and solutions to markets including packaging, infrastructure, transportation, and consumer goods. China is Dow’s second-largest market worldwide, with multiple manufacturing and R&D facilities.

Affected by the recent downturn in the global chemical industry, Dow Chemical has shut down its ethylene cracker and other assets in Europe. Earlier this year, Dow announced the elimination of 4,500 jobs—roughly 13% of its global workforce—in pursuit of its goal to boost annual operating profits by $2 billion.

6. Linde Group

Linde Group is a global leader in industrial gases and engineering, serving industries including chemicals and energy, food and beverage, electronics, healthcare, manufacturing, as well as metals and mining. Founded in 1879, the company is headquartered in the United Kingdom. In 2006, Linde Group acquired BOC, a long-established British gas company, becoming the world’s largest specialized gas and equipment provider and the first specialized gas company to be included in the Fortune Global 500.

In 2025, Linde Group reported chemical sales of US$33.986 billion, ranking sixth on the Global Top 50 Chemical Companies list. While most chemical companies have struggled with declining sales and profits, Linde achieved steady growth across both metrics, posting a profit margin of 27.2%. This underscores that industrial gases are a segment of the chemical industry relatively less susceptible to economic cycle fluctuations.

Linde Group’s strong performance is largely driven by the expanding use of industrial gases such as oxygen and hydrogen across sectors including chemicals, steel, and healthcare. The company is now targeting the space exploration market, expanding its facilities in Florida to supply specialty gases for rocket launches, while also building a new air‑separation plant in Texas to provide oxygen for space exploration and other industrial applications. Last year, Linde also launched an underground helium storage project in Texas.

7. LG Chem

Founded in 1947 and headquartered in Seoul, LG Chem is a subsidiary of the LG Group. As a global leader in the chemical industry, it operates across four major business segments—petrochemicals, battery materials, advanced materials, and life sciences—and maintains 61 subsidiaries worldwide, holding more than 50,000 global patents.

8. Saudi Basic Industries Corporation

Saudi Basic Industries Corporation is a globally leading diversified chemical company headquartered in Riyadh, Saudi Arabia. Established in 1976, SABIC is 70% owned by Saudi Aramco, with the remaining 30% publicly traded on the Saudi Stock Exchange.

In 2025, Saudi Basic Industries Corporation reported chemical sales of US$31.073 billion, ranking eighth on the Global Top 50 Chemical Companies list.

SABIC’s operations span chemicals, commodity and high-performance plastics, agricultural nutrients, and steel, with six strategic business units: Basic Chemicals, Intermediates, Polyolefins, Polyvinyl Chloride and Polyester, Fertilizers, and Metals. Its products are widely used across end markets including construction, medical devices, packaging, agriculture, electronics and electrical appliances, transportation, and clean energy.

To address the sluggish market, Saudi Basic Industries Corporation (SABIC) reached an agreement in January this year to sell its European chemicals business to Aequita. The European operations were the result of SABIC’s strategic expansion beginning in 2000, when the company leveraged its low-cost production advantages to generate substantial cash flow and execute several large‑scale acquisitions in Europe. However, in recent years, the business has struggled with high costs and low selling prices. In 2025, SABIC announced the closure of its ethylene cracker units in the Netherlands and the United Kingdom, and it sold its engineering plastics businesses in Europe and the Americas to Mutares for US$450 million.

9. Air Liquide

Air Liquide, officially known as Air Liquide S.A., is a French chemical company founded in 1902. It specializes in the production and provision of industrial and medical gases, covering oxygen, nitrogen, hydrogen, and rare gases.

In China, the company has established joint ventures with Sinopec—Ningbo Zhenhai Refining & Chemical LyondellBasell Chemical Co., Ltd. and Ningbo Zhenhai Refining & Chemical LyondellBasell New Materials Co., Ltd.—which together deliver over one million tons annually of high‑quality propylene oxide and styrene products to the market. These downstream products are used in sectors such as automotive, electronics, construction, pharmaceuticals, and consumer goods.

To adapt to changing market conditions, LyondellBasell has accelerated its business transformation through strategic realignment. In 2023, it completed the acquisition of Italy’s Mepol Group, expanding its renewable specialty chemicals business, and unveiled a new strategy focused on growing its core businesses while advancing circular and low-carbon solutions. By 2025, LyondellBasell entered into a 12-year renewable electricity agreement with Encavis, helping to achieve its goal of sourcing more than 90% of its electricity from renewable sources.

Affected by the sluggish market, LyondellBasell has gradually withdrawn from the European market in recent years, selling its ethylene cracker facilities in France and Germany, as well as its polypropylene plants in the United Kingdom and Spain, while expanding its operations in lower‑cost countries such as the United States and Saudi Arabia. In 2025, the company’s chemical sales revenue is projected at US$30.153 billion, ranking it 10th on the Global Top 50 Chemical Companies list—two spots lower than the previous year.

The chemical industry—industry within industry.

The chemical industry, often abbreviated as “chemicals,” plays a vital role in transforming basic raw materials into a wide array of products; for this reason, it is frequently referred to as the “industry of industries.” Virtually every industrial sector relies on the chemical industry to function.

Chemical value chain

The chemical industry value chain begins with the extraction of raw materials and ends with end‑use products consumed by consumers or enterprises, encompassing intermediate processing, chemical product manufacturing, and sales.

Raw material extraction refers to the mining or production processes of basic feedstocks such as crude oil, natural gas, coal, minerals, biomass, and air (used for nitrogen production), which primarily supply carbon, hydrogen, oxygen, nitrogen, chlorine, sulfur, and other essential elements for chemical manufacturing. For example, petroleum cracking yields ethylene, propylene, and other fundamental petrochemicals; mined phosphates, potash, and sulfur can be processed into fertilizers; and brine can be used to extract chlorine and caustic soda.

The intermediate processing stage involves converting raw materials into basic chemicals through large-scale chemical processes, which are then used to produce more complex chemicals—such as olefins, aromatics, methanol, and ammonia—at refineries and chemical plants. These intermediates can further be employed in the manufacture of polymers, fibers, and other downstream products. Meanwhile, inorganic chemical plants produce acids (e.g., sulfuric acid, nitric acid), alkalis, industrial gases, and other bulk commodities, typically serving as feedstocks for chemical production or as inputs for manufacturing materials like plastics, synthetic rubbers, and fibers.

The chemical manufacturing stage refers to the process by which chemical enterprises use basic chemicals and intermediates to produce a wide variety of finished chemical products. These products include bulk chemicals—such as polyethylene plastics or chlorine, which are produced in large volumes and relatively standardized—as well as specialty chemicals—such as adhesives, coatings, and additives, which are produced in smaller quantities and offer higher added value—and fine chemicals—such as pharmaceutical raw materials, which are characterized by low production volumes and high purity. Before entering the sales phase, these products undergo blending, formulation, or packaging processes.

The sales stage encompasses distribution and marketing. Many chemicals are sold on a business-to-business basis: bulk customers procure directly, while the needs of small and medium-sized clients are typically met by chemical distributors. These distributors and traders provide warehousing, transportation, and just-in-time delivery services to various end users, ensuring that manufacturers’ products reach the end market efficiently.

Chemical substances ultimately become integrated into end products or industrial processes across the economy, with end users ranging from industrial manufacturers to consumers. In most cases, chemical products are virtually “invisible”—for example, specialized catalysts used in the production of plastic components for electronic devices, or bulk polymers employed in consumer‑goods packaging—so users hardly notice their presence, yet they are ubiquitous.

Sub-sectors of the chemical industry

Based on product type and their position in the chemical value chain, chemical companies can be categorized into: basic chemicals firms, specialty chemicals firms, fine chemicals firms, and integrated or diversified chemical enterprises.

Basic chemicals companies typically produce large volumes of relatively simple‑structured chemicals. Their products serve as feedstocks for the manufacture of other chemicals and materials, including olefins such as ethylene and propylene; aromatics like benzene and toluene; commodity plastics such as polyethylene, polypropylene, and polyvinyl chloride; synthetic fibers like polyester and nylon; inorganic chemicals including chlorine, caustic soda, synthetic ammonia, nitric acid, and sulfuric acid; as well as a wide range of fertilizer products. The majority of global chemical enterprises fall into this category. In China, the chemical industry accounts for approximately 44% of total global chemical sales revenue, with growth driven primarily by the production of basic chemicals.

Specialty chemical companies primarily produce differentiated, high‑value‑added chemicals tailored to specific applications. These products typically feature lower production volumes but command higher selling prices and profit margins. Product categories include functional additives (such as plasticizers and flame retardants), adhesives and sealants, specialty polymers and composite materials, industrial coatings and inks, electronic chemicals (including photoresists), water‑treatment chemicals, mining reagents, fragrances and flavorings, personal‑care ingredients, and pharmaceutical excipients. Specialty chemicals are usually developed through formulation or manufactured to custom specifications. Most such firms are mid‑size companies that focus on core technologies and niche markets, placing a strong emphasis on R&D and technical services. Larger, diversified chemical corporations also establish dedicated specialty‑product divisions, such as BASF’s high‑performance materials and Dow Chemical’s specialty plastics.

Fine chemicals companies are a subcategory of specialty chemicals firms. Their products are characterized by high purity, complex manufacturing processes, and low production volumes; they are typically single‑molecule substances obtained through multi‑step chemical reactions. These include intermediates for pharmaceuticals and other high‑value applications, such as active pharmaceutical ingredients (APIs) and their precursors, high‑purity biochemicals, advanced electronic materials, and sophisticated specialty monomers. Due to their high technological intensity and stringent regulatory requirements, these products generally command premium pricing, underscoring their high value‑added nature. Companies in this sector often operate multifunctional plants capable of producing multiple products or custom‑synthesized compounds—for example, manufacturing a specific anticancer drug intermediate for a pharmaceutical client. The industry comprises a large number of small enterprises, as well as divisions within major chemical corporations.

Integrated or diversified chemical companies typically span multiple segments of the value chain, achieving end-to-end operations that range from basic raw materials to high-value-added products, such as BASF and Dow Chemical.

Economic and Structural Characteristics of the Chemical Industry

The economic characteristics of the various links in the chemical industry’s value chain differ from one another, while also sharing common structural factors.

Capital Intensity: The chemical industry is highly capital-intensive; constructing a world-class ethylene cracker or a fertilizer plant can require investments of several billion dollars, and even after commissioning, these facilities demand ongoing maintenance. According to the American Chemistry Council (ACC), this high capital intensity renders the sector acutely sensitive to financing costs and investment cycles. High fixed costs mean that plants must operate at full capacity to spread out unit costs; during market booms, firms expand capacity, leading to oversupply, followed by a subsequent phase of capacity destocking. Due to substantial capital outlays and stringent technological requirements, most subsectors exhibit significant barriers to entry. Only fine chemicals and specialty chemicals have relatively lower capital thresholds, yet they still necessitate investments in versatile production equipment and the establishment of infrastructure compliant with regulatory standards.

Cost Structure: In the bulk chemicals sector, the core costs are raw materials and energy. Feedstocks such as naphtha and ethane account for a significant share of ethylene production costs, while fuels and electricity underpin reactor operation and separation processes. Companies prioritize securing low‑cost feedstocks and enhancing energy efficiency. By contrast, in the specialty chemicals segment, R&D, technical services, and sales expenses represent a larger proportion of total costs, with firms allocating more revenue to new‑product development and technical support. Fine chemical manufacturing, characterized by complex processes and stringent quality controls, incurs substantially higher labor and quality‑control costs compared to bulk chemicals, where automation is more prevalent. Environmental, health, and safety (EHS) compliance costs are pervasive across the industry, with a particularly high share in large‑scale bulk chemical projects and in fine chemical operations that must meet pharmaceutical‑grade standards.

Pricing Mechanisms: Pricing mechanisms vary significantly across different types of chemical products. Commodity chemicals are primarily driven by global supply and demand and raw-material costs, resulting in substantial price volatility, limited product differentiation, and a largely passive pricing stance among producers. Specialty chemicals, by contrast, exhibit greater price stability; their pricing is more closely tied to the value they deliver to customers and typically accounts for only a small share of downstream total costs, leading to higher customer acceptance of reasonable price increases. Consequently, these products commonly employ negotiated pricing, long-term contracts, or index‑linked floating pricing tied to raw-material benchmarks. Fine chemicals, often produced in customized, low‑volume batches, are priced either on a cost‑plus or value‑based basis; while a few suppliers enjoy considerable bargaining power, the entry of numerous new producers can exert downward pressure on prices. Overall, commodity chemical prices display cyclical fluctuations, whereas specialty and fine chemicals, leveraging their differentiation advantages, tend to command more stable pricing.

Profit Margins and the Profit Pool: As the chemical industry chain extends further downstream toward higher value-added segments, profit margins tend to rise. Basic chemicals exhibit the lowest profit margins, with competitive advantages stemming from economies of scale, supply-chain integration, and access to low-cost feedstocks. Specialty chemicals can achieve gross margins of 30% to 50%, with EBITDA margins ranging from 15% to 25%, driven by pricing power and added value. Fine chemicals, leveraging intellectual property or process complexity, can command exceptionally high gross margins, though they face correspondingly higher R&D and compliance costs. Across the industry, profits are concentrated among two types of firms: commodity‑chemical producers that control low‑cost feedstocks, and companies with differentiated product portfolios. Today, many chemical firms are upgrading into downstream, high‑value‑added segments and launching differentiated products to break free from homogeneous price competition.

Vertical Integration Dynamics: Vertical integration is a core strategic choice in the chemical industry. Upstream integration enables low-cost access to raw materials and hedges against price volatility; Middle Eastern firms, leveraging their abundant, inexpensive domestic oil and gas resources, can maintain strong profitability even during periods of depressed oil prices. By contrast, companies lacking upstream integration capabilities are vulnerable to margin compression from rising feedstock costs. Downstream integration helps lock in market demand and generate additional profits; however, since end‑use manufacturing falls outside the core competencies of most chemical producers, deep downstream integration remains relatively rare, with most firms remaining at the material‑production stage. Product‑chain integration involves further processing high‑risk, low‑value‑added base chemicals such as chlorine into higher‑value products like polyvinyl chloride (PVC). Companies such as BASF, Dow Chemical, and SABIC have achieved a high degree of vertical integration. Those that do not pursue full‑chain integration must build core strengths in operational efficiency and technological expertise, striking a strategic balance between integration depth and operational flexibility.

Overall, the chemical industry is characterized by high fixed costs, strong product‑cycle dynamics, and robust margins for differentiated products. Industry profits are concentrated in niche segments with high barriers to entry and significant differentiation. Companies that leverage cost leadership or diversify their operations to manage cyclical risks, while continuously investing in technological innovation to achieve product differentiation, tend to deliver more resilient financial performance. By contrast, the returns from commodity‑grade chemical production—where differentiation is limited—are closely tied to broader macroeconomic cycles.

A Brief History of the Petrochemical Industry: A Pillar of Global Manufacturing Development

The petrochemical industry is the cornerstone and a core component of modern chemical manufacturing, as well as a pillar of global industrial development. Emerging from humble beginnings in the early 20th century, it has steadily evolved into a powerful, globally influential sector. Although its history is relatively short, it has repeatedly risen to prominence, with a trajectory that is both compelling and transformative—its products have fundamentally reshaped industrial production, economic systems, and everyday life.

Petrochemical products refer to a wide range of chemical compounds derived from petroleum and natural gas, including key basic feedstocks such as ethylene, propylene, butadiene, benzene, toluene, and xylene. These feedstocks serve as the starting point for producing tens of thousands of end-use products, including plastics, fertilizers, synthetic rubber, detergents, solvents, and more.

Humans have been extracting oil and natural gas for centuries, yet converting hydrocarbons into synthetic materials remains a relatively new technological frontier.

Budding

19th century

Although the petrochemical industry only officially took off in the 20th century, its technological roots can be traced back to the 19th century. Initially, the primary use of petroleum was to produce kerosene, which replaced whale oil as an illuminating fuel. However, as electric lighting gradually came to dominate, kerosene’s market position declined accordingly.

During this period, chemists’ understanding of hydrocarbons deepened considerably. In 1856, William Henry Perkin accidentally synthesized the first synthetic dye, mauveine, from coal tar—a byproduct of coal gasification. This breakthrough laid the foundation for the modern organic chemical industry and demonstrated for the first time that hydrocarbons could be transformed into compounds with entirely new properties and commercial value. Although coal tar is derived from coal rather than petroleum, the coal‑tar industry nonetheless provided the chemical and technological groundwork for the subsequent development of the petrochemical industry.

Birth

The 1920s–1940s

In the 1920s, Union Carbide and Dow Chemical Corporation pioneered the production of ethylene from petroleum. This marked the official commencement of large-scale petrochemical production and cemented the United States’ position as the birthplace of the modern petrochemical industry.

Key milestones include: in the 1920s, thermal cracking was applied to the industrial production of ethylene; in the 1930s, synthetic rubber and a variety of synthetic plastics—most notably polyethylene, discovered in the United Kingdom in 1933—were successively introduced; and in the 1940s, World War II served as a catalyst for the further growth and expansion of the petrochemical industry. With the disruption of natural rubber supplies, the United States was compelled to invest in the production of synthetic rubber, while rubber‑stockpiling programs also spurred a dramatic surge in rubber output based on petrochemical technologies.

In addition, key materials such as nylon, styrene, and butadiene—valued for both military and civilian applications—also achieved technological breakthroughs and scaled-up production during this period.

Peace and Prosperity

The 1950s–1960s

Following the end of World War II, the United States—and indeed the entire world—entered a period of economic prosperity. The rapid rise of consumerism fueled robust demand for petrochemical products and spurred their explosive growth.

In the automotive industry, the widespread use of tires and interior‑trim plastics has significantly boosted demand for synthetic rubber; in the packaging sector, polyethylene and polypropylene films have found broad application thanks to their superior performance; in agriculture, petrochemical‑derived fertilizers and pesticides have fundamentally transformed food‑production practices; and in construction, PVC pipes, insulating foams, and synthetic adhesives have gradually replaced traditional building materials, becoming standard industry‑wide components.

In the 1960s, leveraging their proximity to raw material sources and well-developed supporting infrastructure, Houston in the United States, Rotterdam in the Netherlands, and certain regions of the Middle East gradually emerged as major global hubs for the petrochemical industry. Meanwhile, iterative advancements in catalytic cracking and steam cracking technologies significantly boosted both the output and efficiency of petrochemical production, making large-scale manufacturing of light olefins such as ethylene and propylene a practical reality.

The Oil Crisis and Globalization

The 1970s–1990s

The two oil crises of 1973 and 1979 had a profound impact on the global petrochemical industry. As international oil prices soared, chemical companies were compelled to restructure their feedstock supply chains, enhance operational efficiency, and shift from naphtha‑based feedstocks to natural gas liquids (NGLs)—a trend that was particularly pronounced in the United States. Meanwhile, Middle Eastern nations, leveraging the wealth generated by oil exports, began aggressively developing downstream petrochemical industries, giving rise to a new generation of major petrochemical players.

Under the pressure of cost competition, during this period, global chemical companies broadly pursued strategies of scale expansion and vertical integration.

In the 1980s and 1990s, the process of economic globalization accelerated markedly. Japan, South Korea, China, and other countries successively developed large-scale integrated chemical industrial parks, providing crucial support for their rapidly growing industrial economies.

The Rise of the Middle East and Asia

Early 21st century to the 2020s

The first two decades of the 21st century witnessed rapid growth among state-owned chemical enterprises worldwide, with the rise of the petrochemical industries in the Middle East and Asia emerging as one of the most prominent features of this period. Major state-owned chemical companies such as Saudi Basic Industries Corporation, QatarEnergy, and Sinopec achieved swift expansion in scale.

The Middle East, leveraging its得天独厚 (unparalleled)资源优势 of raw materials, utilizes ethane from natural gas to produce petrochemical products at low cost. Meanwhile, with sustained economic growth, China has become the world’s largest consumer of chemical products, driving robust demand in sectors such as plastics, packaging materials, electronic chemicals, and construction materials. Driven by market forces, countries are increasingly building large-scale integrated refining‑and‑chemical production complexes to boost profitability and reduce logistics costs. In addition, environmental concerns have moved to the forefront of public policy and investor considerations, prompting the industry to broadly explore pathways toward a circular economy, product recycling and reuse, and bio-based material alternatives.

Carbon Reduction Pressures and Future Prospects

From the 2020s to the present

Today, the petrochemical industry stands at a crossroads of transformation. While global demand for plastics, fertilizers, and specialty chemicals remains robust, environmental concerns are also drawing increasing attention.

Under this trend, decarbonization has become one of the prevailing movements, with leading chemical companies beginning to invest in low‑carbon technologies such as carbon capture, green hydrogen, and electrochemical cracking. Complementing this, recycling and the circular economy are also gradually taking shape; although supporting infrastructure still requires further development, both mechanical and chemical recycling technologies are advancing steadily.

Digitalization is another key area of development; the application of advanced technologies such as process control, artificial intelligence (AI), and digital twins is continuously enhancing chemical companies’ operational efficiency and maintenance capabilities. Many enterprises are also pursuing new technological pathways, including research into bio-based alternatives and efforts to develop technologies for producing bio‑naphthalene, algae‑derived feedstocks, and renewable ethylene.

Although the industry currently faces significant challenges, global demand for chemical products is expected to grow at a faster pace than demand for fuels. As sectors such as transportation progressively transition to electrification, market demand for polymers, specialty coatings, and high-performance composite materials is also set to continue rising.

Compose a new chapter again

The history of the petrochemical industry is one marked by continuous innovation and remarkable adaptability, placing it among the most influential sectors in shaping the global economy and transforming human life. From early coal‑tar chemistry to today’s state‑of‑the‑art ethylene cracking units and large, smart chemical parks, the petrochemical industry has consistently evolved to meet the diverse material demands of the global market.

As the world transitions toward sustainable development and clean energy, the petrochemical industry must redefine its value proposition—not by abandoning its traditional strengths, but by responsibly developing new technologies and adapting to emerging business models. Chemical companies that proactively adopt low‑carbon solutions, enhance circular‑economy practices, and integrate smart technologies will not only secure their position in this transformative wave but also lead industry-wide change, helping to shape a new landscape for manufacturing and consumption.
