Abstract
This invention relates to a thermally conductive moldable polymer blend comprising a thermoplastic polymer having a tensile at yield of at least 10,000 psi; at least 60% by weight of a mixture of boron nitride powders having an average particle size of at least 50 microns; and a coupling agent. The composition displays a thermal conductivity of at least about 15 W/m.degree. K and it is capable of being molded using high speed molding techniques such as injection molding.
