Patent ID: 7999033

Claim:
A thermoconductive silicone elastomer, the total 100 wt. % of which comprises: 90 to 10 wt. % of a silicone elastomer being a cured body of a hydrosilation-curable organopolysiloxane composition comprising (A) an organopolysiloxane having at least two alkenyl groups in one molecule, (B) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms in one molecule, and (C) a platinum-type catalyst; and the following components dispersed in said silicone elastomer: (D) 0.2 to 5.0 wt. % of a reinforcing fine powder silica; (E) 10 to 90 wt. % of a thermoconductive inorganic powder; and (F) greater than 0 to 10 wt. % of a non-reactive organopolysiloxane that is liquid at room temperature; wherein the cured thermoconductive silicone elastomer has a hardness of 5 to 70 measured by a spring-type hardness tester according to SRIS 0101-1968, a tensile strength above 0.2 MPa according to JIS K 6251, an elongation exceeding 300%, said thermoconductive silicone elastomer demonstrates adherence to a heat-generating member and a heat-radiating member or heat-dissipating member, and said thermoconductive silicone elastomer can be peeled by stretching from a heat-generating member and a heat-radiating member or heat-dissipating member between which said thermoconductive silicone elastomer is sandwiched.
