With the development of petrochemical industry, polyethylene production has developed rapidly and is widely used, such as in plastic prototypes.Polyethylene (PE) is a kind of odorless, non-toxic thermoplastic resin made by polymerization of ethylene. It has excellent low temperature resistance (the lowest use temperature can reach -100~-70°C), chemical stability, and can withstand the erosion of most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.
Properties of Polyethylene
