<p>[PROBLEMS] To provide a fluororubber composition giving a fluororubber in which the surface can have a reduced coefficient of friction and can be rough without the need of mold processing; and a process for producing a crosslinked fluororubber. [MEANS FOR SOLVING PROBLEMS] The fluororubber composition is characterized in that it comprises a polyol-crosslinkable fluororubber, a crosslinking accelerator comprising a quaternary ammonium salt, and a polyol-type crosslinking agent and that the weight ratio of the crosslinking accelerator to the polyol-type crosslinking agent, X (quaternary ammonium salt/polyol-type crosslinking agent), is 0.40-0.60. The process for crosslinked-fluororubber production is characterized by heating the fluororubber composition at a temperature in the range of 200-300°C for 0.1-48 hours optionally after polyol crosslinking.</p> |
