The product is made of low-solidifying point 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 excellent performance on anti-low temperature lubricating, It has a very long service life, superior stability and excellent extreme pressure property in the temperature range -60 deg. --200 deg...Its friction coefficient is far less than that of other greases, and the grease would not be dispersed. The product is a kind of multi-functional lubricating grease which is used widely for oiling all kinds of the bearings of equipment from low temperature to middle-high temperature as well as other friction subassemblies in the field of metallurgy, mine, electric power, auto, machanism, chemical combination and military affairs.
