    摘要: Provided are: a thermally conductive silicone composition which, while having low hardness, exhibits excellent re-workability and excellent long-term stability; and a thermally conductive silicone moulded article obtained by moulding said composition into a sheet shape. The thermally conductive silicone composition includes: an organopolysiloxane (a) which has, in at least molecular side chains, alkenyl groups bonded to silicon atoms, and in which the number of alkenyl groups in molecular side chains is 2-9; an organohydrogenpolysiloxane (b) in which at least both terminals are closed by hydrogen atoms directly bonded to silicon atoms; a thermally conductive filler (c); a platinum group metal-based curing catalyst (d); and an organic antioxidant and/or an inorganic antioxidant as an antioxidant (e). When (L) represents the average number of siloxane bonds in component (a) between silicon atoms having, directly bonded thereto, alkenyl groups in molecular side chains, and (L') represents the average polymerization degree of component (b), L'/L = 0.6-2.3 is satisfied.

    摘要: The present invention provides a silicone compound shown by the formula (1) and having a weight-average molecular weight in the range of 500 to 200,000, R 1 a R 2 b R 3 c R 4 d SiO (4-a-b-c-d)/2 (1), wherein R 1 represents the same or different organic group, R 2 represents a polyoxyalkylene group shown by -C m H 2m -O-(C 2 H 4 O) g (C 3 H 6 O) h R 6 , R 3 represents a branched type monovalent organosiloxane group shown by the following general formula (4), M o M R p D q D R r T s T R t Q u (4), and R 4 represents a monovalent organosiloxane group shown by the following general formula (5) or the general formula (6), MM R D v-i (5), M w D v-1 DR v-2 T R v-3 (6). This provides a silicone compound which has excellent emulsification ability and emulsion stability to silicone oil, and can secure high temporal stability.
