Dry & Solid Lubricant Powders

MoS₂, WS₂, hBN & PTFE Dry / Solid Lubricant Powders

Lower Friction supplies dry lubricant and solid lubricant powders in nano, submicron and micron grades, including tungsten disulfide (WS₂), molybdenum disulfide (MoS₂), hexagonal boron nitride (hBN) and micronized PTFE. These materials are used for dry lubrication, friction and wear reduction, dry-film coatings, high-temperature applications and other industrial lubrication requirements.

Selected grades may also be evaluated as additives in compatible oils, greases, coatings and polymers, depending on the material, particle size and formulation.

Material selection depends on the required lubrication function, carrier system, particle size, operating temperature, load, atmosphere and processing requirements. Lower Friction supplies grades for laboratory evaluation, product development and industrial procurement.

Product scope: Nano, submicron and micron grades of dry and solid lubricant powders for dry-film lubrication, friction and wear reduction, coatings and industrial tribology applications. Selected grades may also be evaluated as additives in compatible oils, greases and other formulated products.

Selection note: Values shown are typical published material properties and are not product specifications or guaranteed performance. Confirm all values against the current TDS and SDS for the selected grade.

Lubricant formulation note: Solid powder can impact viscosity, dispersion stability, filtration, sedimentation, surface finish and compatibility. Performance claims and dosage recommendations should only be made under controlled formulation and application conditions.

Which solid lubricant powder should you evaluate?

Select the requirement closest to your application to see which powder is usually evaluated first.

−

Lowest friction under high load

Evaluate first: WS₂ or MoS₂. Both have very low published dry friction values and good load-carrying capability. PTFE has low friction but creeps under sustained load, and hBN has a much higher friction value, so neither is normally the first choice.

+

Formulating into an oil or grease

+

Service temperature above 400 °C

+

Release and anti-stick surfaces

+

Vacuum, humid or wet environments

+

Electrical insulation or heat dissipation

+

Coatings, inks and polymer compounding

How to Choose a Solid Lubricant Powder

Selection should not be based on particle size alone. It depends on the intended application or formulation and operating requirements, including the carrier medium, substrate, application method, operating temperature, load, atmosphere, filtration and clearance, dispersion method and storage stability. Particle size affects suspension, settling, film thickness, surface finish and processing behaviour. A smaller particle size is not always better.
