UHMW-PE

Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.

Ultra-high molecular weight polyethylene (UHMW-PE) is developing very quickly , before the 1980s, the world's average annual growth rate of 8.5% , after the 1980s , the growth rate as high as 15 % to 20 %. Moreover, China's average annual growth rate of over 30 %. 1978 World consumption of 12,000 ~ 12,500 tons , while in 1990 the world demand of about 50,000 tons , of which the U.S. accounted for 70 %. 2007-2009, China has gradually become the world's plastics factory , super molecular weight polyethylene industrial development is very rapid .

Features ultra-high molecular weight polyethylene pipe

  • High wear characteristics of ultrahigh molecular weight of up to 200 million or more , small abrasion index , 6.6 times higher than normal wear alloy . Greatly improve the life of the pipeline .
  • High impact resistance , the products meet GB1843 standards , the impact toughness of the highest value of the product in an existing engineering plastics .
