Low coefficient of friction. UHMWPE is very resistant, and low coefficient of friction, good self-lubricating, is an ideal bearing bushings, slider, lining materials. Use UHMWPE as friction parts of the device, in addition to improve wear life, it can also receive energy-saving effect. Good chemical resistance. Ultra-high molecular weight polyethylene has good resistance to chemical corrosion properties, in addition to concentrated nitric acid, concentrated sulfuric acid, it will not corrode at all lye, acid, and can be used in a temperature (80 ℃ of concentrated hydrochloric acid, In <20% nitric acid, <75% sulfuric acid is stable, its water, washing liquid is stable.) However, ultra high molecular weight polyethylene plate customized, ultra high molecular weight polyethylene material or a halogenated aromatic compound in the material (particularly at higher temperatures the situation) can easily swell UHMWPE plate, so the quality of ultra high molecular weight polyethylene sheet, when applied to special attention. UHMWPE has a very low coefficient of friction (0.05 to 0.11), it is self-lubricating resistance. UHMWPE dynamic factor rub it under water lubrication is PA66 and POM 1/2, second only to the best self-lubricating plastic polytetrafluoroethylene (PTFE) in the absence of lubrication conditions; when it is sliding or rotating When the form of the work, even better than steel and brass add oil after lubrication. Thus, in the field of tribology UHMWPE known as cost / performance ideal friction material.
