Molybdenum Disulfide

Molybdenum Disulfide

Rose Mill Company is an ISO9001:2008 certified manufacturer that processes industrial minerals and mineral-based chemical products. We operate a 20,000 sf manufacturing facility in Connecticut. Molybdenum disulfide (MoS2) has a very low coefficient of friction and a very high load carrying capacity. It can effectively lubricate to 400o F with oxygen present. These robust properties have made molybdenum disulfide the best dry lubricant for a metal-to-metal lubricant. Often called molybdenum disulphide or moly sulfide, it can be used as a straight powder. It can also be added to oil, silicone, aqueous or solvent-based formulations.

Rose Mill Company can supply Technical Grade (10-30um), Technical Fine Grade (6um) and Super Fine Grade (1um) molybdenum disulfide powder in small and large quantities. Our high-purity powders are available from stock and ship on short notice. Small quantities can be purchased online using the link below. Please call for pricing for large quantities or repeat orders.

Tungsten Disulfide

Tungsten Disulfide (WS2) is the high-temperature cousin of molybdenum disulfide. Tungsten disulfide effectively lubricates in excess of 750oF in the presence of oxygen, and also has a very high load carrying capacity. Tungsten disulfide is effective in metal-to-non-metal applications, such as mold releases and also with plastics, gaskets and other materials.

Rose Mill provides 1um high-purity tungsten disulfide powder from stock.
