ABSTRACT:
A fluoroelastomer composition which contains (a) a fluoroelastomer, (b) at least one member selected from the group consisting of bivalent metal oxide, bivalent metal hydroxide and mixture of bivalent metal oxide or metal hydroxide with metal salt of weak acid, (c) an aromatic polyhydroxy compound, and (d) a quaternary ammonium compound of imidazole or imidazoline, provides a fluoro-rubber having a low compression set and an excellent elastic property. The fluoroelastomer composition can be handled and processed with safety, and yet can be cured at a good cure rate, and has excellent storage properties. The cure rate of the composition is more accelerated by further addition of (e) water or a metal compound which produces water by reacting it with hydrogen fluoride.
