  • Heat conductive BN filler and electrically insulating/heat dissipating sheet
    Patent number: 6054520
    Abstract: A heat conductive BN filler having a cohesive factor of 3-50% is provided. An electrically insulating/heat dissipating sheet is obtained by mixing the BN filler with an organopolysiloxane and a crosslinking agent, shaping the resulting silicone rubber composition into a sheet form, followed by vulcanization. Without special orienting means, the BN particles are oriented in the sheeting step such that their a-axis is perpendicular to the sheet surface.
