Ultra high molecular weight polyethylene (UHMW-PE) is a kind of linear polyethylene with average molecular weight more than 1.5 million. Due to its high molecular weight (20000-300000 for ordinary polyethylene), UHMW-PE has incomparable comprehensive performance compared with ordinary polyethylene and other engineering plastics
1) High wear resistance, 4 times higher than nylon 66 and polytetrafluoroethylene, 6 times higher than carbon steel, is the best of all synthetic resins.
2) The impact strength is 2 times that of polycarbonate and 5 times that of ABS, and it can maintain high toughness at liquid nitrogen temperature (- 196 ºC).
3) The friction coefficient is only 0.07-0.11; It is only 1 / 3-1 / 4 of steel friction coefficient
4) The absorption value of impact energy is the highest among all plastics, and the effect of silencing is very good.
5) Chemical stability is very high, in a certain temperature and concentration range, it can resist all kinds of corrosive media and organic media.
6) Anti adhesion ability is very strong, second only to "plastic king" polytetrafluoroethylene
7) It can be used to contact with food and medicine.
8) The density is the smallest among all engineering plastics, 56% lighter than polytetrafluoroethylene and 22% lighter than polycarbonate; Density is 1 / 8 of steel, etc
Our company uses raw materials with molecular weight more than 5 million to produce UHMW-PE. Due to the above excellent comprehensive performance, UHMW-PE is regarded as "amazing plastic" by European countries and has been widely used in many industries.
