[0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene monomer. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance, and good chemical stability. Because the polymer molecules are connected by carbon-carbon single bonds, they can withstand the corrosion of most acids and alkalis, are insoluble in general solvents at room temperature, have low water absorption, and have excellent electrical insulation. Polyethylene is very sensitive to environmental stress and can be processed by general thermoplastic molding methods. Polyethylene has a wide range of uses and is mainly used to make films.
