The product is made of high-visidity synthetic basal oil, WS2 nanometer particles and some kinds of imported top grade additives according to the latest prescription. It is a new kind of high property anti-grind lubricating grease at home and broad. The product has no obvious dropping point in the temperature range -20 deg. --800 deg. And It has permanent service life, superior stability and excellent extreme pressure property in situation of high temperature and high speed. The friction coefficient is far less than that of other greases, and the grease will not be dispersed also.
