Supply good price transparent white HDPE particles granules raw materials for plastic pipes/plastic bags Recycled materials

High-density polyethylene (HDPE), [commonly known as] low-pressure ethylene, is a white granular product. Non-toxic, tasteless, crystallinity of 80% to 90%, softening point of 125 to 135°C, service temperature up to 100°C; hardness, tensile strength and creep are worse than low density polyethylene; wear resistance, electrical Good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, corrosion resistant to acids, alkalis and various salts; the film has low permeability to water vapor and air, and water absorption Low; poor aging resistance, environmental stress cracking resistance is not as good as 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. High-density polyethylene film has a low heat distortion temperature under stress, so care should be taken when applying it.

         The main advantages of HDPE are: acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and can still maintain a certain degree of toughness at low temperatures. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.

          HDPE resins can be molded into plastic products by injection, extrusion, blow molding, and rotational molding. Various types of containers, industrial accessories, medical supplies, toys, shells, bottle stoppers and shields can be formed by injection molding. Blow molding can be used to form various hollow containers, ultra-thin films, etc. Extrusion can be used to form tubing, stretch tape, strapping, monofilament, wire and cable jacketing and more. In addition, it can also form architectural decorative panels, shutters, synthetic wood, synthetic paper, synthetic film, and calcium-plastic products.
