PE (polyethylene) is a common plastic material, widely used in the field of chemical production raw materials. Its upstream and downstream related products are numerous, which will be described separately below.

Upstream Associated Products:

1. Ethylene: Ethylene is the main raw material of PE and is made into PE through polymerization. Ethylene production methods mainly include naphtha cracking, ethane cracking, coal to ethylene, etc.
2. Catalyst: PE production process requires the use of catalysts, commonly used catalysts include Ziegler-Natta catalysts and Phillips catalysts.

downstream related products:

1. Film: PE can be used to produce various films, such as food packaging film, agricultural mulch film, plastic bags, etc.
2. Pipe: PE can be made into various pipes, such as water supply pipes, drainage pipes, gas pipes, etc., with excellent corrosion resistance, impact resistance and long service life.
3. Container: PE can be made into various containers, such as fuel tanks, chemical tanks, storage tanks, etc., with the advantages of light weight, easy processing, and no rust.
4. Wire and cable: PE can be used to produce the insulation layer and sheath layer of wire and cable, with excellent electrical and mechanical properties.

In short, PE as a common material in the field of chemical production raw materials, its upstream and downstream related products are numerous, a wide range of applications.
