Curable elastomer composition

摘要

A curable fluoroelastomer composition comprising: (a) a fluoroelastomeric copolymer of vinylidene fluoride and at least one other fluorinated monomer; (b) a curing accelerator comprising an iminum compound of the formula <IMAGE> wherein R1 is a substituted or unsubstituted aryl group, R2 is an alkyl or halogenated alkyl group, a cycloalkyl or halogenated cycloalkyl group, or a substituted or unsubstituted aralkyl group, and X is a halogen atom; (c) a polyhydroxy compound as a cross-linking agent; and (d) a metal compound selected from a divalent metal hydroxide, a divalent metal oxide or a mixture thereof.
