MIXTURE OF FLUOROCARBON RUBBER AND SILICONE/ACRYLATE CORE/SHELL RUBBER

摘要

A cross-linkable mixture comprising by weight about a) from 98 to 35 parts by weight of a radically vulcanisable fluorocarbon rubber and b) from 2 to 65 parts by weight of a silicone/acrylate core/shell rubber having a silicone moiety b1) of from 50 to 95 parts by weight and an acrylate moiety b2) of from 5 to 50 parts by weight. 2. A mixture according to Claim 1, wherein the silicone/acrylate core/shell rubber (component b) comprises an at least partially cross-linked core of polyorganosiloxane (b1) and a mantle (shell) grafted thereon of an at least partially cross-linked acrylate copolymer (b2).
