Dry Moly Lubricant - Molybdenum Disulfide (MoS2) Powder

MoS2 Lubricant · Moly Powder · Molybdenum Disulfide Powder

Molybdenum disulfide powder, commonly known as MoS2 powder, moly powder or dry moly lubricant, is a grey, dry/solid lubricant with the chemical formula MoS2 and a hexagonal, lamellar crystal structure. Its layered structure allows the production of low-friction coatings on suitable surfaces.

Lowerfriction is a molybdenum disulfide powder supplier for industrial lubrication and laboratory research. The product portfolio covers dry lubrication, grease and oil additives, coatings, polymers, cold metal forming and vacuum applications.

Product availability: The product brochure includes 90 nm, 1.5 micron, 4.5 micron and 12.5 micron MoS2 powder. Current category listings cover the 1.5, 4.5 and 12.5 micron products; confirm 90 nm stock, custom sizes, pricing, pack size and current product data before ordering.

Performance note: Lubrication performance depends on particle size, surface preparation, carrier medium, humidity, load, temperature and operating environment. The brochure and SDS list conflicting melting/decomposition values, so validate this attribute technically before publishing or using it in production.

Industrial applications of MoS2 lubricant powder

Application	How MoS2 powder is used	Selection note
Dry and solid lubrication	Applied dry or used to generate a solid lubricating layer on appropriate surfaces.	Confirm the surface preparation, humidity, load and operating temperature.
Grease and oil additives	Added to suitable grease and oil systems to improve lubricity and load-bearing capacity.	Check dispersion, carrier compatibility and performance of the final formulation.
Cold metal forming and extreme pressure	Used when a dry lubricant coating and excellent load-bearing capabilities are needed.	Do process trials for substrate, pressure and application technique.
High vacuum and inert atmospheres	Recommended when traditional liquid lubricants may move, evaporate or are not suited.	Check pressure, atmosphere, temperature and compatibility of components.
Paints, coatings and polymers	Additive for suitable coatings, paints, polymers and other solid systems to decrease friction.	Select particle size based on film thickness, surface polish and dispersion process.
Laboratory and research use	Used in research on lubricant behaviour, coatings and chosen material applications.	Check grade, particle size, documentation and handling controls before use.

Choosing an MoS2 powder grade

Particle size influences dispersion, coating thickness, surface quality and processing behaviour. The brochure lists a finest size of 90 nm, with 1.5, 4.5 and 12.5 micron grades as progressively coarser alternatives. The final choice should consider the carrier medium, substrate, application process, film thickness, operating environment, temperature, load and target quantity.
