WS2, MoS2, hBN & Graphite Nano Lubricant Additives
Engine oil additive powders are solid particles evaluated in oils to modify friction and wear under load. This category covers nano and submicron lubricant powders for controlled formulation development, tribology testing and performance research.
Lowerfriction offers 90 nm tungsten disulfide (WS2), 90 nm molybdenum disulfide (MoS2), 70 nm hexagonal boron nitride (hBN), 50 nm graphite and 400 nm graphite powders. The materials can be evaluated in appropriate engine oils, industrial oils, greases, coatings and other systems for dispersion, filtration, settling, additive-package compatibility and finished-lubricant performance, depending on the tests conducted.

Specification note: Particle size, purity, shape, packaging and performance vary depending on the product and grade. The 400 nm graphite product does not represent a nanopowder. Please check the existing specification before making an order.
| Material | Possible use | Other evaluation areas | Formulation note |
|---|---|---|---|
| WS2 | Low-friction solid additive in suitable oils and greases. | High-load contact, dry films, precision components, vacuum research. | Check dispersion, filtration, settling, concentration and surface compatibility. |
| MoS2 | Solid lubricant additive candidate. | Dry lubrication, polymer, metal-forming and tribology. | Performance varies by particle, carrier, atmosphere and formulation. |
| hBN | Application-specific additive. | Thermal management, release, high-temperature lubrication, coatings, polymers. | Check carrier compatibility, dispersion, temperature and required properties. |
| Graphite | Solid lubricant / friction modifier. | Coatings, dry lubrication, polymer and tribology. | Compare nano vs submicron grades. |
Engine oil formulation note: Solid powders applied to engine oil may result in changes in viscosity, filterability, sedimentation, additive-package balance and component compatibility. Dosage and performance should not be prescribed or suggested before controlled formulation and engine-relevant testing.
| Application | Evaluation | Relevant materials |
|---|---|---|
| Engine oil & automotive lubricant development | Powder-form friction and wear modifier in base oil. | Graphite, WS2, MoS2, hBN |
| Industrial oils and greases | Controlled formulation testing. | WS2, MoS2, Graphite, hBN |
| Wear and tribology | Defined load, speed, temperature and lubrication conditions. | All listed grades |
| Dry / solid-film lubricants | Solid lubricant coating. | WS2, MoS2, Graphite, hBN |
| High-load precision mechanisms | Low-friction solid layer. | WS2, MoS2 |
| Thermal / release investigations | Anti-stick and thermal systems. | hBN |
| Coatings and polymers | Slip, friction and release tests. | Graphite, hBN, MoS2 |
| Scientific institutions | Material comparison and dispersion studies. | All listed grades |
The additive package and operating requirement, not particle size alone, are the primary considerations in selection. Check dispersion stability, filterability, sedimentation, component clearance, operating temperature, load and test method. Particles of a smaller size don't necessarily translate to the most ideal lubricant system.

Nano engine oil additive powders are finely divided solid materials, which are assessed as additives in suitable engine oil formulations. They can be studied for friction, wear, load-related or thermal performance, but cannot be regarded as full engine oil additive packages.
This category contains 90 nm WS2, 90 nm MoS2, 70 nm hBN and 50 nm graphite nanopowders. A submicron-grade graphite powder with a size of 400 nm is also available.
Selection depends on the oil or carrier, the additive package in use, the dispersion method, filtration and clearance limits, operating temperature, load and the aim of the test. Application testing prior to production is required.
Never add raw powder to a finished engine oil without a technical evaluation. Direct addition can impact sediment properties, filters, oil flow, additive balance and component compatibility. Use controlled formulation and bench or engine testing instead.
No. The 400 nm graphite grade is larger than the nano range and is better described as a submicron powder. It can be used alongside nanopowders in comparative lubricant studies.
Yes. When requesting documents, include the material, preferred particle size, intended lubricant application, quantity and delivery location.
Product documentation notice: These powders are raw materials for technical evaluation. Specifications, hazards, handling requirements and performance depend on the product, formulation and application. Check the current product specification and Safety Data Sheet prior to testing or use.
