Molybdenum disulfide (MoS2) has chemical stability and good thermal stability, large surface area, high surface activity, is a solid lubricant with excellent catalyst. Along with the MoS2 particle size, its adhesion and coverage are improved significantly in the friction material on the surface, antiwear and friction reducing properties can be improved obviously. Name of a commodity Average particle size Purity Form The specific surface area Bulk density Color Nano molybdenum disulfide 40nm 99.5% Spherical 120m2/g 0.98g/cm3 Dark gray Mainly used in machinery lubrication and friction industry, can be used as solid lubricating material. In the high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-high vacuum conditions, has excellent lubrication nature of equipment. Adding in the lubricating oil, grease, PTFE, nylon, paraffin, stearic acid can improve the lubrication and friction reducing effect, prolong the lubrication cycle, reduce cost, improve working conditions. Also can be used as stripping agent and lubricant nonferrous metal forging.
