<p>A problem to be solved by the present invention is to provide a method for producing a fluororubber composition and a crosslinked fluororubber product which is clean from no detection of sulfate ions, has a high specific gravity and good physical properties in the aspect of elongation at breakage. The crosslinked fluororubber composition includes a fluororubber polymer, at least one kind selected from the group consisting of a bismuth metal and a bismuth compound (other than those containing a sulfate ion, a sulfide ion and a halogen ion) and a crosslinking agent, and at least one kind selected from the group consisting of said bismuth metal or said bismuth compound is included in an amount of 50 to 200 pts. wt. based on 100 pts. wt. of said fluoropolymer.</p> |
