PROBLEM TO BE SOLVED: To provide a perfluoroelastomer composition capable of forming a seal material excellent in mechanical strength while maintaining good heat resistance (permanent compression set properties) without blending an organic filler, and to provide a seal material using the same and a method for producing the same.SOLUTION: There are provided: a perfluoroelastomer composition which comprises 100 pts.wt of a perfluoroelastomer containing a constitutional unit derived from tetrafluoroethylene, a constitutional unit derived from perfluoro(alkylvinylether) or perfluoro(alkoxyalkylvinylether) and a constitutional unit derived from nitrile group-containing perfluorovinylether, 1 pt.wt or more and less than 25 pts.wt of a fluorine resin and a predetermined crosslinking agent; a seal material comprising a crosslinked product of the perfluoroelastomer composition; and a method for producing the same. |
