Key hBN Properties and Applications
Key Material Characteristics
- Low-friction, lubricating material
- Electrically insulating
- Thermally conductive
- Useable in formulations for high temperatures
Common Application Areas
- Lubricating oils and grease formulations
- Dry-film coatings and bonded lubricant coatings
- Thermal conductivity – electrical insulation compounds
- A range of polymer, resin and ceramic types of backfillers
- Mold-release formulations
- Selected metal-forming and glass-processing applications
Ultimately, suitability will depend on how well the material is dispersed, concentration, carrier agent, substrate and operating conditions.
General hBN Reference Values
| Coefficient of friction | 0.15–0.70 |
|---|---|
| Thermal stability in air | Up to 1,000°C |

| Thermal stability in inert atmosphere | Up to 1,800°C |
These are the general hBN reference values and are not batch-specific test data for MK-hBN-150.
Safety, Handling and Storage
Keep powder in a tightly closed container in a dry, well-ventilated area away from moisture. Avoid creating or inhaling dust. Use appropriate local ventilation, gloves and eye protection when handling.
The common MK-hBN-xxx SDS will state that the product is not WHMIS controlled and not classified under GHS, however dust could cause irritation to the respiratory tract, skin or eyes. Please consult the SDS prior to use.

Frequently Asked Questions
What does 1.5 micron APS mean?
APS is by definition the average particle size. Granulation size (average 1.5 micron) is reported here, but does not represent complete particle-size distribution.
What applications can MK-hBN-150 be evaluated for?
It can be tested for lubricating compounds, dry-film compounds, thermal-management compounds, electrical-insulating materials, polymer or ceramic filling, and some mold-release applications.
How should the powder be stored and handled?
Store in a dry, well-ventilated area, tightly closed. Do not expose the product to moisture, do not inhale dust and follow product handling directions outlined in the SDS.
Are the brochure and SDS specific to the 1.5 micron grade?
No. Common information for various grades of hBN powder is included in the brochure and SDS. The purity, particle size, SKU, price and pack options shown on this page relate to MK-hBN-150.
