High-density polyethylene (HDPE)

PRODUCT DESCRIPTION

High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its hardness, tensile strength and creep are better than those of low-density polyethylene; it has good wear resistance, electrical insulation, toughness and cold resistance; it has good chemical stability, is insoluble in any organic solvent at room temperature, and is resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air, and low water absorption; it has poor aging resistance, and its resistance to environmental stress cracking is not as good as that of low-density polyethylene, especially thermal oxidation will reduce its performance, so antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency. The heat deformation temperature of high-density polyethylene film is low under stress, so be careful when using it.

PRODUCT USES

High-density polyethylene resin can be used to form plastic products by injection, extrusion, blow molding and rotational molding. Injection molding can be used to form various types of containers, industrial accessories, medical supplies, toys, shells, bottle stoppers and shields. Blow molding can be used to form various hollow containers, ultra-thin films, etc. Extrusion molding can be used to form pipes, stretch strips, strapping tapes, monofilaments, wires and cable sheaths, etc. In addition, it can also form architectural decorative panels, blinds, synthetic wood, synthetic paper, synthetic films, and molded calcium plastic products, etc.
