    摘要: The present invention includes crosslinked perfluoroelastomeric compositions and molded articles formed from a cross-linkable perfluoroelastomeric composition having a first curable perfluoropolymer having a cure site monomer and a second perfluoropolymer having a cure site monomer. The molar ratio of the tetrafluoroethylene monomer to perfluoroalkylvinyl ether in one perfluoropolymer is about 0 to 100 to about 65 to 35 in the perfluoropolymer. The molar ratio of the tetrafluoroethylene monomer to the perfluoroalkylvinyl ether monomer in the second polymer is about 65:35 to about 95:5 in the second perfluoropolymer. The composition further includes a curative. One fluorine-containing elastomer composition herein, having a short crosslinking time, has perfluoroelastomers (A) having a tetrafluoroethylene unit, a perfluoralkylvinyl ether unit (a) and a monomer unit (b) having at least one kind selected from the group consisting of a nitrile group, a carboxyl group and an alkoxycarbonyl group, wherein the composition has two or more kinds of perfluoroelastomers (A) having differing contents of perfluoroalkylvinyl ether unit (a).
