HDPE (High Density Polyethylene, referred to as "HDPE"), is a kind of High crystallinity, nonpolar thermoplastic resin. Square one HDPE appearance has milk-white, in a small cross section in a certain degree of translucent. PE has excellent resistance to most of the life and the characteristics of industrial chemicals. Certain kinds of chemicals can produce chemical corrosion, such as corrosive oxidant (nitric acid), aromatics () and halogenated hydrocarbon (CTC). The polymer is not hygroscopic and has a good waterproof steam, can be used for packaging purposes. HDPE has the very good performance, especially high insulation dielectric strength, make it very suitable for wire and cable. In the level of high molecular weight has excellent impact resistance, even at room temperature under 40 f low temperature are so...Acid and alkali resistance, organic solvent resistance, good electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, stiffness and mechanical strength higher than that of LDPE, close to PP, than PP toughening, but the surface finish is better than PP.
