Dry / Solid Lubricant Powders
Dry Lubricant Additive Powders
MoS₂, WS₂, hBN & PTFE Lubricant Additive Powders
Lower Friction supplies dry lubricant additive powders in nano, submicron and micron grades, including MoS₂, WS₂, hBN and micronized PTFE. These solid lubricant powders can be evaluated in oils, greases, coatings, polymers, dry films and other industrial formulations.
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 grade powders of raw solid lubricant additive. They are designed to be used in technical evaluations of compatible oils, greases, coatings, polymers and other industrial formulations. They are not full lubricant additive packages or treatments.
Available dry lubricant additive powders
| Product family | Grade / SKU | Listed particle size | Common evaluation / selection |
|---|---|---|---|
| Tungsten Disulfide Powder | MK-WS2-06 | 0.6 micron listed | WS₂ lubricant additive for oils, greases, dry films, high-load sliding surfaces and precision components. |
| Molybdenum Disulfide Powder | MK-MoS2-15 / 45 / 125 | 1.5, 4.5, 12.5 micron; nano grades on request | Lubricant additive for oil, grease, dry lubrication, metal forming, coatings, polymers and vacuum. |
| Hexagonal Boron Nitride Powder | Multiple grades | 70 nm; 0.5, 1.5, 5, 30 micron | High-temperature lubrication, release, thermal management, coatings. |
| Micronized PTFE Powder | MK-PTFE-270 | 3 micron (D50 ≤3 micron) | Dry lubricant additive for oils, greases, coatings, inks and polymers. |
Specification note: Particle size, purities, packaging and performance parameters are dependent on material and grade. Nano, submicron and micron powders can have different dispersion, settling, film formation, filtration and finished system performance characteristics.
Solid lubricant additive comparison
All four powders reduce friction, but they reach their limits for different reasons. The table below sets out the published material properties that usually decide which one is evaluated first.
| Property | WS₂ | MoS₂ | hBN | PTFE |
|---|---|---|---|---|
| Typical dry coefficient of friction | ~0.03 | ~0.03–0.06 | ~0.15–0.7 | ~0.05–0.10 |
| Service temperature in air | to ~450 °C | to ~350 °C | to ~900 °C | to ~260 °C |
| Service temperature in vacuum or inert gas | to ~1300 °C | to ~1100 °C | to ~1800 °C | to ~260 °C |
| Load carrying capability | Very high | Very high | Moderate | Low; creeps under load |
| Behaviour in humid air | Tolerant | Performance drops | Stable | Stable |
| Behaviour in vacuum | Well suited | Well suited | Application-dependent | Outgassing and creep concerns |
| Electrical behaviour | Semiconducting | Semiconducting | Insulating | Insulating |
| Thermal conductivity | Low | Low | High | Very low |
| Chemical inertness | Good | Good | Excellent | Excellent |
| Grades listed here | 0.6 micron | 1.5, 4.5, 12.5 micron | 70 nm; 0.5 to 30 micron | 3 micron |
Selection note: Figures are typical published material properties and indicate starting points, not product specifications or guaranteed performance. Confirm every value against the current TDS and SDS for the grade being considered.
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?
Open the requirement closest to your application to see which powder is normally assessed first, and which one is usually ruled out.
−
Lowest friction under high load
Evaluate first: WS₂ or MoS₂. Both have very low published dry friction values and carry high contact loads. PTFE has low friction but creeps under sustained load, and hBN sits an order of magnitude higher on friction, so neither is the usual first choice here.
+
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

Dry lubricant applications and lubricant additive uses
| Application | Description | Evaluate first | Not usually suitable |
|---|---|---|---|
| Oil & grease additives | Friction reduction and load carrying | WS₂, MoS₂ | hBN |
| Industrial formulations | Lubricant formulations | WS₂, MoS₂, PTFE | — |
| Dry / solid-film lubrication | Solid lubricant coatings | WS₂, MoS₂ | — |
| High load / metal forming | Very high pressure lubrication | MoS₂, WS₂ | PTFE, hBN |
| High-temperature release | Anti-stick applications | hBN | PTFE, MoS₂ |
| Coatings, paints and inks | Adjust slip, friction and release | PTFE | — |
| Polymers | Improve tribological and thermal properties | PTFE, hBN | — |
| Vacuum mechanisms | Where oils and greases are unsuitable | WS₂, MoS₂ | PTFE |
| Humid or wet service | Where moisture is present in operation | hBN, WS₂, PTFE | MoS₂ |
| Electrical insulation | Where conductivity must be avoided | hBN, PTFE | WS₂, MoS₂ |
Choosing a solid lubricant additive powder
It is not particle size alone that drives selection, but the intended formulation and operating requirement. Check the carrier medium, substrate, application method, operating temperature, load, atmosphere, filters and clearance, dispersion method and storage stability. Particle size influences suspension, settling, film thickness, surface finish and behaviour during processing — a smaller particle is not necessarily better.
