A fluororubber composition whereby a vulcanizate having excellent blister resistance can be obtained, the fluororubber composition being obtained by blending 10-100 parts by weight of wollastonite surface-treated with a silane coupling agent and having an aspect ratio of 2 or greater and 0.5-10 parts by weight of a polyol-based cross-linking agent per 100 parts by weight of a fluororubber comprising 60-100 wt% of a solid fluororubber polymer and 40-0 wt% of a liquid fluororubber polymer. Preferably, from the perspective of both cost and ensuring blister resistance, 30-70 wt% of the wollastonite surface-treated with a silane coupling agent is substituted with wollastonite not surface-treated with a silane coupling agent. |
