HDPE is a thermoplastic polyolefin produced by the copolymerization of ethylene. This universal material is constantly developing new uses and markets.


High density polyethylene, English name is “High Density Polyethylene”, abbreviated as “HDPE”. HDPE is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals.


Hardness, tensile strength and creep are better than low density polyethylene; good abrasion resistance, electrical insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, acid and alkali resistance Corrosion of various salts; film has low permeability to water vapor and air and low water absorption; poor aging resistance and environmental stress crack resistance is not as good as low density polyethylene, especially thermal oxidation will reduce its performance, Therefore, it is necessary to add antioxidants and ultraviolet absorbers to the resin to improve this deficiency. High-density polyethylene film has a lower thermal deformation temperature under stress.



High-density polyethylene resin can be molded into plastic products by injection, extrusion, blow molding, and rotational molding. Various types of containers, industrial accessories, medical supplies, toys, shells, stoppers and shields can be formed by injection molding. Various types of hollow containers and ultra-thin films can be formed by blow molding. Extrusion can be used to form pipes, stretched tapes, strappings, monofilaments, wire and cable jackets, etc.
In addition, it can also be used for building decorative panels, shutters, synthetic wood, synthetic paper, synthetic membranes, and molded calcium plastic products.
