Heat-curable silicone rubber composition

摘要

A Heat-curable silicone rubber composition comprising (A) 100 weight parts organopolysiloxane with the average unit formula RxSiO(4-x)/2 each R is independently selected from the group consisting of hydroxyl and substituted and unsubstituted monovalent hydrocarbon groups and x has a value from 1.9 to 2.1 and containing at least 2 silicon-bonded alkenyl groups in each molecule, (B) 10 to 100 weight parts reinforcing filler, (C) 0.1 to 10 weight parts carbosiloxane dendrimer that contains at least 3 silicon-bonded hydrogen atoms in each molecule, and (D) 0.1 to 10 weight parts organoperoxide. ri
