A filling and foaming composition, which can be adjusted to an appropriate viscosity during foaming, can be foamed at an appropriate expansion ratio, and can obtain a sufficient reinforcing effect on members after foaming, To provide a filling foam member and a filling foam. The composition for filling and foaming is prepared by kneading a diene rubber containing 10 to 60% by weight of an epoxidized diene rubber having a number average molecular weight of 500 to 20,000, a crosslinking agent, a curing agent, a foaming agent and a filler. The mounting member 3 is attached to the composition 1 for filling and foaming to produce a foamed filling member P, which is installed in the inner space of the pillar 2 and foamed so that the volume expansion ratio becomes 2.0 times or more. By cross-linking and curing, the filling foam 6 is formed, and the interior space of the pillar 2 is filled. [Selection diagram] Fig. 1 |
