Detailed Product Description: | The performance of ultra-high molecular weight polyethylene (UHMWPE) UHMWPE is a linear polymer relative molecular mass of 50 - 10 million. In addition to the performance of general HDPE, UHMWPE also has outstanding wear resistance, low friction coefficient and lubrication; excellent stress cracking resistance, high temperature creep shape and resistance to low temperature (applicable even in the -269 ° C) ; excellent tensile strength, high impact strength at low temperatures do not drop; good noise damping; the same time, excellent chemical stability and resistance to fatigue; surface adsorption force, excellent electrical insulation properties; toxicity excellent overall performance. (1) The wear resistance of UHMWPE wear resistance ranks highest in the plastic, and more than some metal, compared with other engineering plastics, mortar of UHMWPE wear index is only 1/5 of PA66, HDPE and PVC, 1/10; compared with the metal is 1/7 of carbon steel, brass, 1/27. Such a high resistance to abrasion, general plastic wear test method that is difficult to test the abrasion, which designed a mortar wear testing device. UHMWPE wear resistance and the relative molecular mass is proportional to the relative molecular mass of the higher, the better the wear resistance. (2) the impact resistance of UHMWPE impact strength among the best in all engineering plastics, the impact strength of UHMWPE is about 2 times the impact resistance of PC, ABS, POM and PBTP more than 10 times. Impact resistance, high strength, and that usually impact test method is difficult to make the fracture process. Its impact strength is improved, with the relative molecular mass increases and reaches its maximum in the relative molecular mass of 1.5 million, then gradually decreased with the relative molecular mass continues to rise. Is worth noting that, in liquid nitrogen (-196 ° C) can maintain excellent impact strength, after repeated shocks, a higher surface hardness. (3) polar self-lubrication UHMWPE friction coefficient (0.05-0.11), so the self-lubricity, excellent. UHMWPE dynamic friction coefficient under water lubrication PA66 and POM 1/2, after the self-lubricating plastic polytetrafluoroethylene (PTFE) in the absence of lubrication conditions; the form of a slide or rotate , even better than steel and brass lubricating lubrication. (4) except for chemical resistance in addition to strong oxidizing acid, in a certain temperature and concentration range of ability of a variety of corrosive media (acid salt) and organic media (naphthalene solvent). (5) The impact energy absorbent impact to absorb the value of the highest among all plastic, and thus the noise damping is very good, with excellent effect of the silencer. |
