Abstract
PURPOSE: A heat-radiating sheet having excellent electric insulation, thermal conductivity, etc., and being useful as a material for heat-radiators of integrated circuits, containing as principal components, a synthetic rubber and an inorganic filler containing in a specific volume ratio, boron nitride, alumina, silica, etc.
CONSTITUTION: (a) Boron nitride and (b) at least one member selected from the group consisting of alumina, silica, magnesia, zinc white and mica are mixed together so as to produce (A) an inorganic filler having a volume ratio of the component (a) to the component (b), of 0.3W3. Then, (A) the resulting organic filler and (B) a synthetic rubber having electrical insulating properties, such as silicone rubber, fluoro-rubber or ethylene/propylene rubber are mixed together so as to provide a mixture having 35W70vol% of the component (A). The sheet of the purpose is obtained by molding the above mixture into sheet and hot-curing or pressurecuring the sheet. The sheet is placed between a heat-generating electronic part and a radiating fin.
