Information

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.

High density polyethylene prices china

High-density polyethylene has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. At room temperature, it is insoluble in any organic solvent, resistant to corrosion by acid, alkali and various salts; the film has low permeability to water vapor and air, and low water absorption; poor aging resistance, environmental cracking resistance is not as good as low density polymer Ethylene, especially thermal oxidation, will reduce its performance, so the resin needs to be added with antioxidants and ultraviolet absorbers to improve and improve this deficiency. The heat distortion temperature of high-density polyethylene film under stress is lower, which should be paid attention to when applying.
