PROBLEM TO BE SOLVED: To provide a silicone rubber composition having low hardness and high impact resilience, particularly capable of giving a silicone rubber suitable for shaping a roll and to provide a silicone rubber molded article obtained by curing the silicone rubber composition. SOLUTION: The composition is an addition reaction type silicone rubber composition composed of as the base polymer a mixture between 50-98 wt.% of a polyorganosiloxane, which has on an average 0.05-0.25 mol% of an alkenyl group in the molecule terminals and the monovalent unsubstituted or substituted hydrocarbons on the intermediate siloxane units and has an average degree of polymerization of 3,000-20,000, and a remainder consisting of a polyorganosiloxane having 0-2 alkenyl groups in the molecule. The silicone rubber molded article obtained by curing it is suitable for rolls in particular. COPYRIGHT: (C)2005,JPO&NCIPI |
