Key hBN Properties and Applications
Key Material Characteristics
- Low-friction, lubricating material
- Electrically insulating
- Thermally conductive
- Suitable for evaluation in high-temperature formulations
Common Application Areas
- Dry-film and bonded lubricant coatings that stick to the surface
- Thermally conductive and electrically insulating compounds
- The fillers are a mixture of polymer, resin and ceramic
- Mold-release formulations
- A range of selected metal forming and glass processing applications
Final suitability is dependent on dispersion, concentration, carrier medium, substrate and operating conditions.

Frequently Asked Questions
What does 5 micron APS mean?
APS refers to the average particle size. The particle size, indicated as the average particle size 5 micron, should not be considered as a complete particle-size distribution.
What applications can MK-hBN-500 be evaluated for?
It can be used to assess lubricant formulations, dry-film lubrication, thermal-management compounds, and electrical-insulating materials, as well as some mold-release applications.
How should the powder be stored and handled?
Store in a dry well-ventilated area. Keep away from dust or contamination by air and stick to handling procedure provided in the SDS.
Are the brochure and SDS specific to the 5 micron grade?
No. Common information is provided in the brochure and SDS for various grades of hBN powder. The purity, particle size, SKU, price and pack types mentioned on this page are applicable for MK-hBN-500.
