Additve in high-quality special oils and specialty greases for improving the frictional properties. The product grade BN-03 is a fine, highly de-agglomerated powder which will have lower tendency to settle up in the oil dispersion. Therefore, this grade is suitable for applications in which the product is to be used both in oils and in greases.
Other grades with different particle size distributions are available, so that an accurate adjustment can be made to the final product.
Boron nitride is also used as an additive for increasing the thermal conductivity in plastics, for which we recommend mainly the quality BN-35.
