Key hBN Properties and Applications
Key Material Characteristics
- Low-friction, lubricating material
- Electrically insulating
- Thermally conductive
- Quite compatible for evaluation within high-temperature formulation
Common Application Areas
- Formulations of lubricating oils and grease
- Both dry-film and bonded lubricant coatings can be applied
- Thermal conductor and electrical insulator compounds
- A range of polymer, resin and ceramic fillers are used
- Mold-release formulations
- A few applications in the metal forming processes and glass processing were selected for modelling
Final suitability is dependent on dispersion, concentration, carrier medium, substrate and operating conditions.

Safety, Handling and Storage
Keep in a well-ventilated room where moisture doesn't get to the powder and store in a tightly closed container. Don't make or breathe in dust. Use appropriate local ventilation, gloves and eye protection when handling.
The material is listed as not WHMIS controlled, and not classified as dangerous under GHS, from the common MK-hBN-xxx SDS, but that dust may irritate the respiratory system, skin or eyes. Read the SDS before using.

Frequently Asked Questions
What does 70 nm APS mean?
APS is an abbreviation for average particle size. The value of 70 nm represents the average particle size – this is not a full size distribution.
What applications can MK-hBN-N70 be evaluated for?
It can be assessed for use in lubricants, dry-film coatings, thermal-management compounds, electrical-insulation materials, or polymer or ceramic fillers and some mold release applications.
How should the powder be stored and handled?
Store in a well-ventilated, dry area and tightly capped container. Keep away from moisture, from airborne dust and follow the handling instructions outlined in the SDS.
Are the brochure and SDS specific to the 70 nm grade?
No. Common information which is applicable to numerous hBN powder grades is found in the brochure and SDS. The details listed on this page are for the purity, particle size, SKU, price and pack size of MK-hBN-N70.
