1. HDPE products must bear a certain pressure, usually choose large molecular weight, better mechanical properties HDPE resin.It is several times stronger than ordinary polyethylene products (PE products)
2. Among all engineering plastics, HDPE’s wear resistance ranks first.The higher the molecular weight of the material, the more wear resistance, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.).
3. HDPE has high temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance, in addition to electrical insulation and impact resistance, cold resistance performance is also very good, mainly used in thermoforming, blow molding, injection molding and other fields
4. Melting point is different: polyethylene has a melting point of 100-130c. Its low temperature resistance is excellent.The melting point range of high-density polyethylene is 132-135℃, when heated to the melting point, it can be recycled and reused
