CPE (chlorinated polyethylene) plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive. The following are some of the upstream and downstream associated products related to CPE:

1. Upstream associated products:

(1) Polyethylene (PE):CPE is made by chlorination of polyethylene, so polyethylene is the main raw material of CPE. Polyethylene is a thermoplastic with excellent low temperature resistance, electrical insulation, creep resistance and chemical resistance.

(2) Chlorine gas: Chlorine gas is an important raw material for chlorinating polyethylene. Chlorinated polyethylene is generated by reacting chlorine gas with polyethylene.

2. Downstream related products:

(1) Wire and cable: CPE has excellent oil resistance, flame resistance and chemical resistance, so it is widely used in the manufacture of wire and cable, especially for the manufacture of oil resistance, flame retardant, corrosion-resistant wire and cable.

(2) Rubber products: CPE can be used as a rubber modifier to improve the wear resistance, aging resistance and oil resistance of rubber, so it is widely used in the manufacture of rubber products, such as tires, hoses, tapes, etc.

(3) Waterproof membrane: CPE has good weather resistance, aging resistance and water resistance, so it is widely used in the manufacture of waterproof membranes, such as waterproof membranes, waterproof coatings, etc.

In short, as an important chemical raw material, CPE has a wide range of upstream and downstream related products, involving many fields, such as wire and cable, rubber products, waterproofing materials, etc.
