Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene monomers. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, waxy, and has excellent low-temperature resistance (the lowest operating temperature can reach -100~-70°C). It has good chemical stability. Because the polymer molecules are connected by carbon-carbon single bonds, it can withstand the corrosion of most acids and alkalis (not resistant to oxidizing acids). It is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation.

Polyethylene is very sensitive to environmental stress (chemical and mechanical effects) and can be processed by general thermoplastic molding methods. Polyethylene has a wide range of uses, mainly used to make films, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulation materials for televisions, radars, etc.

Product uses

High-pressure polyethylene: more than half is used for film products, followed by pipes, injection molded products, wire wrapping layers, etc.

Medium and low-pressure polyethylene: mainly injection molded products and hollow products.

Ultra-high pressure polyethylene: Due to its excellent comprehensive properties, ultra-high molecular weight polyethylene can be used as an engineering plastic.
