MicroLubrol Hexagonal Boron Nitride (hBN, hex boron nitride, "white graphite"), 2.5 micrometers (microns, µm, micrometers), approximately 5000 mesh equivalent ("mesh" is a measure of the fineness of a material separation screen, but due to the impossibility of weaving such fine wires or filaments to produce such a fine screen there are no actual screens with mesh finer than 600 available, so the number is for relative particle size comparison only). <br><br> NOTE: The Hexagonal Boron Nitride (hBN) product offered here is NOT cosmetic grade and has not been tested for use in cosmetics or any other regulated use.
