Abstract
Proposed is a polyol-crosslinkable fluorocarbon rubber-based composition which exhibits excellent workability in milling and molding as well as excellent storage stability and is capable of giving a molded and vulcanized rubber article at a high vulcanization velocity with good mold-releasability of the molded and vulcanized rubber article from the metal mold. The rubber composition comprises, as the essential ingredients: (a) a polyol-crosslinkable fluorocarbon rubber and (b) a crosslinking agent which is, in place of a conventional polyol compound such as bisphenol A, a silylated polyol compound such as 1,1,1,3,3,3-hexafluoro-2,2-bis(4-trimethylsiloxy phenyl) propane, i.e. a silylation product of bisphenol AF.
