How did petrochemicals contribute to the growth of plastics synthetic rubber synthetic fibres detergents and fertilizers after 1945?

After 1945, the petrochemical industry expanded rapidly by utilizing hydrocarbon feedstocks—primarily olefins and aromatics—derived from crude oil and natural gas to manufacture a wide array of essential materials.12

• Plastics and Synthetic Rubber: Through processes like catalytic cracking, refineries produced building blocks such as ethylene, propylene, butadiene, and benzene. These were converted into polymers like polyethylene, polystyrene, and various synthetic rubbers, which became foundational to modern manufacturing.12
• Synthetic Fibres: Petrochemical derivatives, particularly those sourced from ethylene and xylene, enabled the mass production of synthetic fibres like polyester, which transformed the textile industry.1
• Fertilizers and Detergents: The industry utilized synthesis gas to produce ammonia, a primary component of fertilizers, while sulfur recovered during oil purification provided the raw materials for sulfuric acid, further supporting fertilizer production.13

By tailoring these chemical processes, the industry moved beyond simple fuel production to create the diverse chemical building blocks that define modern consumer goods.12
