Abstract
Disclosed is a fluoroelastomer composition comprising (1) a fluoroelastomer which comprises tetrafluoroethylene, a perfluoro (C1-C5 alkyl vinyl ether) or a perfluoro (C3-C11 (alkoxyalkyl) vinyl ether) and a cyano group-containing perfluorovinyl ether, (2) a hydrotalcite compound, (3) a crosslinking agent and (4) carbon black. The fluoroelastomer composition has excellent metal corrosion inhibition properties, and particularly, this composition generates only small amount of a corrosive material when exposed to high temperatures.
