Abstract
There are provided a composition for silicone rubber foam, a manufacturing method of a silicone rubber foam, and a silicone rubber foam in which it is possible to control the foaming states. The composition for silicone rubber foam contains: (A) 100 parts by mass of polyorganosiloxane having a degree of polymerization of 4,000 to 10,000 and having two or more alkenyl groups at a content of 0.001 mmol/g or more and less than 0.3 mmol/g; an amount of polyorganohydrogensiloxane having an average of two or more Si-atom-bonded hydrogen atoms so that a molar ratio of the hydrogen atoms to the alkenyl groups in the (A) component is 0.001 to 5; 0.1 to 10 parts by mass of an organic foaming agent with a decomposition temperature of 50 to 250° C.; 5 to 200 parts by mass of silica powder; and a catalyst amount of a platinum-based metal catalyst activated with ultraviolet rays.
