Polyethylene (English name: polyethylene, PE for short, is a kind of thermoplastic by polymerization of vinyl resin. In industry, including ethylene and small amounts of alpha olefin copolymer. Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance (the lowest temperature can reach 70 ~ 100 ℃), chemical stability is good, most of acid and alkali erosion (acid) with characteristics of oxidation resistance, temperature does not dissolve in solvents, small water imbibition, good electrical insulation performance
Introduction to the
Polyethylene is a semicrystalline thermoplastic materials. Their chemical structure, molecular weight and degree of polymerization and other performance are largely dependent on the use of polymerization methods. Polymerization methods determines the type of the branched chain and the branched chain. Chemical structure and processing conditions of polymer crystallinity depends on.
