Polyethylene, abbreviated as PE, is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes ethylene and a small amount of α－ Copolymers of olefins. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance (with a minimum usage temperature of -70~-100 ℃), good chemical stability, resistance to most acids and alkalis (not resistant to oxidizing acids), insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation performance; But polyethylene is very sensitive to environmental stress (chemical and mechanical effects) and has poor heat aging resistance. The properties of polyethylene vary depending on the variety and mainly depend on the molecular structure and density. Different production methods can yield products with different densities (0.91~0.96g/cm3). Polyethylene can be processed using general thermoplastic molding methods (see Plastic Processing). It has a wide range of uses, mainly used for manufacturing thin films, containers, pipelines, monofilament, wires and cables, daily necessities, etc., and can be used as high-frequency insulation materials for television, radar, etc

Type of PE:

(1) LDPE: Low density polyethylene, high-pressure polyethylene

(2) LLDPE: Linear Low Density Polyethylene

(3) MDPE: Medium density polyethylene, bimodal resin

(4) HDPE: High density polyethylene, low pressure polyethylene

(5) UHMWPE: Ultra High Molecular Weight Polyethylene

(6) Modified polyethylene: CPE, cross-linked polyethylene (PEX)

(7) Ethylene copolymer: ethylene propylene copolymer (plastic), EVA, ethylene butene copolymer, copolymer of ethylene other olefins (such as octene POE, cyclic olefins), ethylene unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH)
