Polyethylene, with excellent low temperature resistance (minimum use temperatures up to -70~-100), good chemical stability, resistant to most acid and alkali erosion (not with oxidation properties of acid-resistant), not soluble in common solvents at room temperature, water absorption of small, excellent electrical insulating properties; but the polyethylene to environmental stress (chemical and mechanical action) is very sensitive to heat aging poorly. 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.
