Key hBN Properties and Applications
Key Material Characteristics
- Low-friction, lubricating material
- Electrically insulating
- Thermally conductive
- Can be used in high temp formulations
Common Application Areas
- Write formulations for lubricating greases and oils
- Dry-film and bonded coatings of lubricants
- Thermoconductive, electrically insulating compounds
- These are filled with polymer, resin and ceramic
- Mold-release formulations
- Selected metal-forming and glass-processing applications
However, final suitability will depend on dispersion and concentration, carrier medium, substrate and operating conditions.

Safety, Handling and Storage
Store in a dry and well-ventilated area and keep powder dry to keep it safe from moisture. Don't cause or breathe in any dust from air. Use appropriate local ventilation, gloves and eye protection when handling.
The common MK-hBN-xxx SDS states that the material is not WHMIS controlled and not classified as dangerous by GHS however dust has the potential to irritate the respiratory tract, skin or eyes. Review Safety Data Sheet before using.

Frequently Asked Questions
What does 0.5 micron APS mean?
APS is the average particle size (microns). The product is packaged with an average particle size of 0.5 micron – this is not to be interpreted as a full particle size distribution.
What applications can MK-hBN-050 be evaluated for?
It can be evaluated for use in lubricant formulations, dry-film and bonded coatings, thermally conductive or electrically insulating compounds, polymer and ceramic fillers and specific mold-release, metal-forming and glass-processing applications.
How should the powder be stored and handled?
Store in a dry, well-ventilated area, tightly sealed. Keep out of moisture, prevent airborne dust and adhere to the handling procedure provided in the SDS.
Are the brochure and SDS specific to the 0.5 micron grade?
No. The information provided in the brochure and SDS is a generic piece of information for a variety of hBN powder grades. Purity, particle size, SKU, price and pack shown on this page are for MK-hBN-050 only.
