High-density polyethylene (HDPE) is a white powder or granular product. Non-toxic, tasteless, crystallinity is 80%～90%, softening point is 125～l 35℃, service temperature can reach 100℃; hardness, tensile strength and creep are better than low density polyethylene; wear resistance, 

Good electrical insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, and resistant to corrosion by acids, alkalis and various salts.
