<P>PROBLEM TO BE SOLVED: To provide a heat-conductive elastomer composition that can be recycled, does not contain a compound resulting in contact failure of electric circuits, has a suitable heat conductivity, hardness to be favorably attached closely to a heat generating member, etc., and extensibility to follow strain due to thermal expansion of heat generating members, or the like, and a molded article. <P>SOLUTION: The heat-conductive elastomer composition to become a material of a molded article is obtained by mixing 100 pts.vol. of a mixture, prepared by blending 100 pts.mass of a hydrogenated thermoplastic styrene-based elastomer (E) that is a hydrogenated block copolymer, has a weight-average molecular weight of 150,000-500,000 and contains 20-50 mass% of a styrene-based monomer, 50-200 pts.mass of a rubber softener having a kinematic viscosity (40°C) of 50-500 cSt and 50-300 pts.mass of an olefin-based resin, with 40-400 pts.vol. of a surface-coated aluminum hydroxide and/or a surface-coated magnesium oxide as a heat-conductive filler, and has an elongation percentage based on JIS K6251 of ≥100%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
