Momentive Performance Materials PolarTherm® PTX25 Boron Nitride (BN) Powder
Categories:	Ceramic; Nitride; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Spherical BN Agglomeration Powder. Spherical nature may improve thermal conductivity at moderate loading levels when used as a filler in polymers or lubricants, and produce less anisotropic properties. Features of BN include thermal conductor, electrical insulator, low dielectric constant, high temperature stability, lubricious, inert, and non-wetting.
