Polyethylene no smelly, nontoxic, feel like wax, has excellent of resistance low temperature performance (minimum using temperature can up -70~-100 ℃), chemical stability good, ability most acid alkali of erosion (not resistance has oxidation nature of acid), at room temperature Xia not dissolved Yu General solvent, absorbent small, electric insulation performance excellent; but polyethylene for environment stress (chemical and mechanical role) is is sensitive of, heat aging sex poor. Properties vary depending on the variety of polyethylene, depends on molecular structure and density. Using different production methods can have different densities (0.91~0.96g/cm3) of the product. Polyethylene thermoplastic molding methods that are available (see plastic processing) processing.
