摘要： The present invention provides a peroxide-vulcanizable fluorine-containing elastomer composition which is remarkably improved in fluidity and thereby exhibits improved processability, though conventional fluorine-containing elastomer compositions could be molded only by a molding process having a problem in its productivity, for instance, compression molding or transfer molding which has been used so far as a general molding process. The present invention further provides a molded article obtained by vulcanizing the composition. The present invention also provides a fluorine-containing elastomer composition in which a large amount of a filler can be blended. Specifically, the present invention relates to the fluorine-containing elastomer composition comprising a fluorine-containing elastomer (A) composed of a structural unit derived from vinylidene fluoride and/or a structural unit of tetrafluoroethylene and a structural unit derived from at least one other monomer, and having (a) a number average molecular weight (Mn) of 30,000 to 70,000 g/mol, and (b) an iodine content of 0.3 to 1.0% by weight and an organoperoxide vulcanizing agent (B).
