ABSTRACT:
A fluoroelastomer composition which contains (a) a fluoroelastomer, (b) at least one metal compound 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, (d) a quaternary ammonium compound of 8-alkyl- or 8-aralkyl-1,8-diaza-bicyclo[5.4.0]-7-undecenium, and (e) 1,8-diaza-bicyclo[5.4.0]-7-undecene in an amount of not more than 0.07 part by weight per 100 parts by weight of fluoroelaster, 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 with an appropriate induction time and a good cure rate, and has excellent storage properties.
