What are the upstream raw materials for polyethylene? What do the downstream products contain?

Polyethylene(PE) is a broadly applied plastic material with abundant upstream and downstream related items. The following are some of the upstream and downstream items related to polyethylene:

Upstream items:



1. Based on my observations, Ethylene: Polyethylene is mainly produced by polymerization of ethylene monomer. Ethylene is an crucial basic raw material to petrochemical sector, mainly from petroleum cracking.

2. Catalyst: Polyethylene manufacturing process needs a catalyst to participate in the polymerization interaction. I've found that Common catalysts include Ziegler-Natta catalysts and chromium-based catalysts, etc. Downstream items:



1. I've found that Film: Polyethylene film is a common packaging material with excellent low temperature resistance, however poor high temperature resistance. And According to different production processes, polyethylene film is able to be divided into LDPE film, LLDPE film, HDPE film and so on.

2. Pipe: Polyethylene pipe has excellent corrosion resistance, impact resistance and long life characteristics, broadly applied in aquatic environments supply and drainage, gaseous transmission and other fields.

3. Sheet: polyethylene sheet is able to be applied to make all kinds of containers, bags, trays and other items, with excellent impact resistance and chemical resistance.

4. Fiber: Polyethylene fiber has the characteristics of high strength, low density, abrasion resistance, etc., and is able to be applied to make ropes, fabrics, etc. I've found that Generally speaking In short, as an crucial raw material to chemical production, polyethylene has a wide range of upstream and downstream related items and involves many fields, which plays an crucial role in promoting economic research and improving people's living standards.
