HDPE stands for high-density polyethylene, a white powder or granular product. Non-toxic, tasteless, crystallinity is 80%～90%, softening point is 125～135℃, service temperature can reach 100℃; hardness, tensile strength and creep are better than low-density polyethylene; wear resistance, electricity Good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, corrosion resistance to acids, alkalis and various salts; low 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 lower thermal deformation temperature under stress, so pay attention to it when applying it.
