Full Text
- (A) 2.0 to 8.0 mol % of vinylidene fluoride,(B) 60.0 to 70.0 mol % of tetrafluoroethylene,(C) 35.0 to 25.0 mol % of perfluoro(lower alkyl vinyl ether) or perfluoro(lower alkoxy-lower alkyl vinyl ether), and(D) 0.2 to 3.0 mol % of a perfluoro unsaturated nitrile compound, and having a Mooney viscosity ML1+10(121° C.) of 65 to 110, as well as a vulcanizable fluorine-containing elastomer composition comprising said fluorine-containing elastomer and a bisamidoxime compound in an amount of 0.2 to 5 parts by weight based on 100 parts by weight of the fluorine-containing elastomer. A sealing material obtained by vulcanization-molding of the fluorine-containing elastomer has not only excellent compression set characteristics and plasma resistance, but also low adhesion to metal at a higher temperature, specifically 150° C.
