Abstract
The present invention provides a fluororubber composition that has excellent heat resistance and excellent mechanical properties at high temperatures. The fluororubber composition comprises a peroxide cross-linkable fluororubber (A); a carbon black (B); a peroxide cross-linking agent (C); and a low-self-polymerizing cross-linking accelerator (D), wherein to 100 parts by mass of the fluororubber (A), the amount of the carbon black (B) is 5 to 50 parts by mass, the amount of the cross-linking agent (C) is 0.01 to 10 parts by mass, and the amount of the cross-linking accelerator (D) is 2.5 parts by mass or smaller.
