Abstract
The present invention relates to a boron nitride composition of particles of boron nitride and a nonionic surfactant for use as a filler with a distribution of agglomerates having an average particle size in the range of between 20-80 microns and to a molding compound having a high thermal conductivity of above at least 5 W/m.degree. K. The molding compound comprises a polymer base material, a filler and a nonionic surfactant with the filler comprising boron nitride in a concentration of at least 60% by weight of said composition and wherein the nonionic surfactant is selected from the class consisting of carboxylic acid amides and carboxylic acid esters.
