PURPOSE: To obtain a silicone rubber composition for producing a shrinkable molded body shrinkable by irradiation of microwaves without requiring heating.
CONSTITUTION: This composition comprises (a) an organopolysiloxane expressed by the average compositional formula RaSiO(4-a)/2 [R in the formula is the same or different and a 1-10C unsubstituted or substituted monovalent hydrocarbon group and at least two thereof in the molecule are vinyl groups; (a) denotes a number of 1.95-2.05], (b) a reinforcing silica filter, (c) a thermoplastic resin, (d) a microwave-absorbing substance and (e) a cross-linking agent. Furthermore, this composition is free of the component (d) when R in the component (a) is 3,3,3-trifluoropropyl group or 2-cyanoethyl group.
