UHMWPE (UHMW-PE) is viscosity-average molecular weight of more than 1.5 million linear polyethylene. UHMW-PE because of its high molecular weight (general polyethylene for 2-30 million), with ordinary polyethylene and other works by the incomparable and the integrated use of performance: 1) high wear resistance than nylon and Teflon 66 high four times, six times higher than carbon steel, synthetic resin is present in all the best. 2) high impact strength, 2 times for polycarbonate, ABS five times, but also in the temperature of liquid nitrogen (-196 â??) to maintain high toughness. 3) and good self-lubricating, self-lubricating and a PTFE, the friction coefficient for 0.07-0.11; friction of steel for the 1/3-1/4. 4) can absorb shocks in the value of all plastics as the highest, mufflers good effect. 5) high chemical stability, to a certain temperature and concentration within the capability of various aggressive media and the role of organic medium. 6) anti-adhesion strong, second only to "plastic Wang" Teflon. 7) completely non-toxic health and can be used for contact with food and medicine. 8) density in the smallest of all engineering plastics, light PTFE than 56%, 22% light than polycarbonate, conspiracy to steel 1 / 8, and so on. Since the integrated use of the excellent performance, UHMW-PE Europe and the United States was known as "amazing plastic" and attention
