Chemicals Supply Chain

The petrochemical industry chain covers the entire process from extracting raw materials such as oil and natural gas to manufacturing final products.

• Upstream：Crude oil, light oil, gasoline, diesel, kerosene, fuel oil, lubricating oil refined from crude oil, and related drilling equipment.
• Midstream：basic petrochemical raw materials such as ethylene, propylene, butadiene, benzene, phenol, etc., produced by pyrolysis of upstream raw materials as well as the chemical raw materials such as plastics, rubber, and artificial fibers made of the above-mentioned raw materials through chemical reactions such as polymerization, esterification, and alkylation.
• Downstream：daily necessities used in food, clothing, housing, and transportation made of plastic, rubber, artificial fiber, and other chemical raw materials. They include plastic products, rubber products, cleaning agents, artificial fibers, color dyes, adhesives, plasticizers, pesticides, cosmetics, etc., with a wide range of applications.
