Hexagonal boron nitride has one of the highest thermal conductivities for an electrically insulating material, with an added benefit of superior thermal shock resistance. As a platelet or agglomerated powder, it acts as an effective filler in polymers for thermal management. As a solid, its thermal shock resistance and inertness make it suitable for high-temperature ceramic manufacturing and molten metal processing.

With a dielectric strength much greater than alumina, BN is an excellent low loss insulator. BN is an outstanding dielectric cooling filler for polymer compounds used in LED lighting and electronic assemblies for power devices or RF/high frequency applications.

The strong, covalent bonding of BN coupled with B2O3 passivation at platelet edges makes for a very inert material. BN is oxidation and corrosion resistant, making it suitable for high-temperature processes such as steel processing and ceramic manufacturing. Additionally, it can serve as a P-Type dopant for semiconductor manufacturing as a planar diffusion source. As an inert material, it is also non-toxic for use in cosmetics or non-contact food grade lubricant additives.

BN -- thanks to its extreme lubricity, oxidation resistance and non-abrading properties -- is ideal as a release agent in light-metal processing and as a lubricant additive in dynamic friction materials for high-performance automotive and aerospace applications. It’s low hardness makes it very easy to machine parts with tight tolerances, such as nozzles for metal atomization or side dams and break rings for steel casting.

BN can impart unique optical properties to compounds such as automotive varnish and cosmetic formulas. A wide selection of platelet sizes offers control over finish and opacity - from translucent to opaque, matte to shiny. Additional benefits in cosmetic formulations include oil absorption and optical blurring to reduce the appearance of scratching or fine lines. Its natural white color makes it easy to add to any formulation with dyes.
