HEAT CONDUCTIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a heat conductive sheet of superior conductivity in a sheet thickness direction and of high productivity, which is simple to manufacture at a low cost. SOLUTION: In an organic matrix material, boron nitride powder which contains secondary cohesion body particle, whole diameter is 50μm or more, by 1-20 wt.% as a heat conductive filler is dispersed and mixed. It is desirable that the organic matrix materials be silicone rubber.
