Silicone rubbers with improved mold release properties

摘要

The invention relates to polyorganosiloxane rubber compositions which vulcanize to elastomers under the influence of heat and comprise A) 100 parts by weight of organopolysiloxane, B) 10 to 200 parts by weight of filler, C) 0.1 to 10 parts by weight of crosslinking agent which forms free radicals and D) 0.05 to 10 parts by weight of aliphatic alcohol with C8- to C30-alkyl radicals. The aliphatic alcohol (D) acts as an internal mold release agent.
