Title: HEAT TRANSFER SHEET AND METHOD FOR PRODUCING HEAT TRANSFER SHEET
Abstract:
A heat transfer sheet which contains an acrylic polymer, 70-75% by volume of a high-soda alumina, and 2.7-5.3% by volume of a magnesium hydroxide that is coated with a higher fatty acid and has a smaller particle diameter than the high-soda alumina. This heat transfer sheet has a compression force required for a deformation at a compression rate of 20% or less of 200 N or less, and a thermal resistance of 0.45°C/W or less.
