Abstract:
1. A composition for silicone rubber foam comprising: (A) 100 parts by mass of alkenyl group-containing polyorganosiloxane expressed by a following general formula (A1), having a mass average degree of polymerization of 4,000 to 10,000 and having two or more R where R (B) an amount of polyorganohydrogensiloxane having an average of two or more hydrogen atoms bonded to a silicon atom in a molecule so that a molar ratio of the silicon-atom-bonded hydrogen atoms to the alkenyl groups in the (A) component (the number of moles of hydrogen atoms bonded to the silicon atoms in the (B) component/the number of moles of the alkenyl groups in the (A) component) is 0.001 to 0.26; (C) 0.1 to 10 parts by mass of an organic foaming agent with a decomposition temperature of 50 to 250° C.; (D) 5 to 200 parts by mass of silica powder; and (E) a catalyst amount of a platinum-based metal compound catalyst activated with ultraviolet rays.
