Ultra high molecular weight polyethylene (UHMW-PE) is linear polyethylene with an average molecular weight of more than 1.5 million. Due to its high molecular weight (ordinary POLYETHYLENE 20-300,000), UHMW-PE has comprehensive properties that ordinary polyethylene and other engineering plastics cannot match:
1) High wear resistance, 4 times higher than nylon 66 and ptfe, 6 times higher than carbon steel, is currently the best of all synthetic resins.
2) High impact strength, 2 times of polycarbonate, 5 times of ABS, can still maintain high toughness at liquid nitrogen temperature (-196℃).
3) Good self-lubrication, its self-lubrication is similar to ptfe, friction coefficient is only 0.07-0.11; Only 1/3 to 1/4 of the friction coefficient of steel.
4) The absorption value of impact energy is the highest in all plastics, and the effect of noise elimination is very good.
5) High chemical stability, in a certain range of temperature and concentration can withstand the action of various corrosive media and organic media.
6) Strong adhesion, second only to "plastic king" PTFE.
7) Completely sanitary and non-toxic, can be used to contact with food and drugs.
8) The density is the smallest of all engineering plastics, 56% lighter than ptfe, 22% lighter than polycarbonate; One eighth the density of steel, and so on
