Product Usage

Polyethylene is a thermoplastic resin produced by the addition polymerization of ethylene, and its molecular structure contains only carbon and hydrogen elements. It is non-toxic, has excellent low-temperature resistance (minimum operating temperature can reach -100℃), and good chemical stability. Polyethylene can be processed into films, wire and cable sheaths, pipes, various hollow products, injection molded products, fibers, etc., and is therefore widely used in agriculture, packaging, automobiles, and other fields.
