Title: FLUORINE-CONTAINING ELASTOMER MIXTURE, METHOD FOR PRODUCING SAME, COMPOSITION FOR VULCANIZING PEROXIDE, AND MOLDED ARTICLE
Abstract:
Provided are: a fluorine-containing elastomer mixture capable of providing a molded article which has low hardness and low fuel permeability while sustaining the good cold resistance possessed by a cold-resistant fluorinated rubber; a composition, which contains said fluorine-containing elastomer mixture, for vulcanizing a peroxide; and a molded article obtained from said composition for vulcanizing a peroxide. A fluorine-containing elastomer mixture comprising: (A) a fluorine-containing elastomer capable of vulcanizing a peroxide containing an iodine atom, which is either a copolymer (a1) exclusively consisting of 50-85 mol% of a vinylidene fluoride unit and 15-50 mol% of a perfluoro(alkyl vinyl ether) unit, or a copolymer (a2) exclusively consisting of 45-85 mol% of a vinylidene fluoride unit, 1-30 mol% of a tetrafluoroethylene unit and 14-30 mol% of a perfluoro(alkyl vinyl ether) unit; and (B) a fluorine-containing elastomer having a fluorine content of 70.0% or more and being capable of vulcanizing a peroxide containing an iodine atom.
