THERMALLY CONDUCTIVE SILICONE GEL COMPOSITION AND THERMALLY CONDUCTIVE SILICONE GEL SHEET AND METHOD FOR PRODUCING SAME

摘要

A thermally conductive silicone gel composition according to the present invention contains the following components A to D. A : a straight-chain organopolysiloxane that contains one vinyl group at each of the two terminals of the molecular chain and that has a kinematic viscosity of 1-600 mm2/s; B : a straight-chain organopolysiloxane that contains at least three Si-H groups in each molecule and has an Si-H group content of 0.05-6 mol/kg, in an amount that provides number of Si-H groups in component B/number of vinyl groups in component A = 0.2-0.5; C : a platinum catalyst in a catalytic amount; and D : a thermally conductive filler at 300-1,000 mass parts per 100 mass parts of the total amount of A and B.
