Combinations of polyorganosiloxanes and fluororubbers containing double bonds by Si-H addition

摘要

A chemically linkable mixture comprising (a) about 98 to 80% by weight of a fluoroelastomer bearing lateral olefinic double bonds, (b) about 2 to 20% by weight of at least one of a silicone oligomer, silicone elastomer and a fluorosilicone elastomer containing Si-H groups, and (c) a catalyst containing at least one of a noble metal and an organic peroxide. Fluororubbers made therefrom are distinguished by excellent physical properties.
