- The English name of polyethylene: polyethylene, referred to as PE, is a thermoplastic resin made by the polymerization of ethylene. Industrially, it also includes copolymers of ethylene and small amounts of -olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (minimum use temperature can reach -70 -100 ), good chemical stability, can withstand most acid and alkali erosion (not resistant to oxidizing properties) Acid), insoluble in common solvents at room temperature, low water absorption, and excellent electrical insulation properties.
Polyethylene is sensitive to environmental stresses (chemical and mechanical effects) and has poor thermal aging resistance. The properties of polyethylene vary from species to species, mainly depending on the molecular structure and density. Products with different densities (0.91 to 0.96 g / cm3) can be obtained by using different production methods. Polyethylene can be processed by common thermoplastic molding methods (see Plastic Processing). It has a wide range of uses, mainly used to manufacture films, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulation materials such as televisions and radars. With the development of petrochemical industry, polyethylene production has developed rapidly, and the output accounts for about 1/4 of the total plastic output. In 1983, the total polyethylene production capacity in the world was 24.65Mt, and the capacity of devices under construction was 3.16Mt.
