Abstract
A vulcanizable fluorine-containing elastomer composition having excellent stability in molding and kneading property, from which a vulcanized article having a small compression set can be produced in a short period of time. The vulcanizable fluorine-containing elastomer composition comprises a vulcanization agent, a vulcanization aid and a fluorine-containing elastomer having C—H bond in its polymer chain, and an optimum vulcanization time T90 (min) of the composition and a compression set CS (%) of the vulcanized article satisfy the following equations (I) and (II):
