Products overview: 
High-density polyethylene (HDPE), white powder or granular product. Non-toxic, tasteless, crystallinity is 80%~90%, softening point is 125~135℃, and the service temperature can reach 100℃; hardness, tensile strength and creep are better than low density polyethylene; wear resistance, electrical Good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvent at room temperature, corrosion resistance of acid, alkali and various salts; thin film permeability to water vapor and air, 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 pay attention to it when applying it.
