Molybdenum Disulfide Powder (MoS2)

Molybdenum Disulfide Powder Lubricant and Additive

Molybdenum disulfide (moly) is an inorganic compound comprised of sulfur and molybdenum with the chemical formula MoS2. This material is naturally found as the mineral Molybdenite. Moly is an excellent lubricant due to its layered molecular structure and low coefficient of friction; Moly is also used as a semi-conductor and catalyst in non-lubricant applications. Few cost-effective alternatives exist which offer high lubricity and stability at high temperatures and pressures. Moly may be used as a powder lubricant or a lubricating additive in water, solvent, oil, and grease-based lubricants. We help manufactures select the correct grade of moly powder for their needs. We also offer a number of formulated lubricants, greases, and pastes fortified with Molybdenum Disulfide. Contact us today for assistance.
