what is polyethylene
- May 08, 2018 -

PE is a kind of thermoplastic resin made from ethylene.In industry, it also includes copolymers of ethylene and small amounts of alpha-olefin.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, excellent electrical insulation properties;But polyethylene is very sensitive to environmental stress (chemical and mechanical), and it has a poor aging resistance.The properties of polyethylene vary from breed to breed, depending on the molecular structure and density.The product of different density (0.91 ~ 0.96g/cm3) can be obtained by different production methods.Polythene can be processed by plastic forming method of general thermoplastic (see plastic processing).It is widely used for making film, container, pipe, single wire, wire and cable, daily necessities, etc., and can be used as high frequency insulation material for TV, radar and so on.
