Products Description of Molybdenum disulfide CAS#1317-33-5

Molybdenum disulfide, the main component of molybdenite, is a lead-gray to black solid powder. It feels greasy to the touch and has no odor. It belongs to the hexagonal or orthorhombic system, is similar to graphite, and has a metallic luster. Molybdenum disulfide is a good solid lubricant material. It has excellent lubricity for equipment under conditions of high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum. It can be used as a friction modifier (friction reducer), anti-wear agent, extreme pressure agent and antioxidant. It is widely used in the aviation industry (vacuum anti-radiation lubrication), automobile industry (fixtures and components), anti-seizure industry (mechanical industry) (general lubrication), mining industry, military industry, shipbuilding industry, heavy industry, bearing industry, gear industry and assembly industry, etc. It is also used as an additive for various lubricants, the manufacture of molybdenum compounds, catalytic hydrogenation desulfurization catalysts, gas storage materials, photovoltaic cell materials, etc.

Product Application of Molybdenum disulfide CAS#1317-33-5

Widely used in the automotive industry and the mechanical industry. Can be used as a good solid lubricant. It has excellent lubricity for equipment under high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum conditions. Adding it to lubricating oil, grease, polytetrafluoroethylene, nylon, paraffin, stearic acid can improve lubrication and reduce friction. It can extend the lubrication cycle, reduce costs, and improve working conditions. It can also be used as a demolding agent for non-ferrous metals and a lubricant for forging dies.
