Key hBN Properties and Applications
Key Material Characteristics
- Low-friction, lubricating material
- Electrically insulating
- Thermally conductive
- Can be used in high-temp compositions
Common Application Areas
- Formulations designed to lubricate oils and greases
- Dry film and bonded lubricant coatings
- Thermally conductive (TC), electrically insulating (EI) compounds
- The fillers of polymers, resin and ceramics
- Mold-release formulations
- Metal-forming and glass-processing have been selected as applications
Final suitability depends upon dispersion, concentration, medium in which dispersed, substrate & operating conditions.
General hBN Reference Values

These values are hBN "reference" values and DO NOT represent batch test results for MK-hBN-3000.
Safety, Handling and Storage
Keep the powder in a tightly closed container in a dry, well-ventilated area and keep it away from moisture. Try to prevent the generation or breathing in of dust. Use appropriate local ventilation, gloves and eye protection when handling.
The common MK-hBN-xxx SDS states that it is not WHMIS controlled and not classified as dangerous as per GHS, however, dust can irritate the respiratory tract, skin or eyes. Check SDS before using.

Frequently Asked Questions
What does 30 micron APS mean?
APS is the term used for the average particle diameter. This is found to be the average particle size for the product and does not reflect a complete particle-size distribution.
What applications can MK-hBN-3000 be evaluated for?
It can be tested for lubricants, dry film lubrication, thermal-management, electrical insulators, polymer fillers, selected mold release applications and ceramic fillers.
How should the powder be stored and handled?
Store in a cool, dry, ventilated area, tightly closed. Keep away from moisture and airborne dust and use as outlined in the SDS.
Are the brochure and SDS specific to the 30 micron grade?
No. Common information of several hBN powder grades can be found in the brochure and in the SDS. The purity, particle size, SKU, price and pack information listed on this page apply to MK-hBN-3000.
