Abstract
There is provided a fluorine-containing elastomer composition assuring easy kneading and providing a crosslinked article having improved strength. The fluorine-containing elastomer composition comprises (A) an elastomer of a vinylidene fluoride/hexafluoropropylene copolymer having a branching coefficient of 30 to 300 ppm, a Mooney viscosity (ML: 121° C.) of 7 to 80 and a molecular weight distribution (Mw/Mn) of 1.5 to 4, and (B) an elastomer of a vinylidene fluoride/hexafluoropropylene copolymer having a storage modulus G' at 180° C. at 500 cpm of 500 to 900, and a mass ratio of (A)/(B) is 70/30 to 90/10.
