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 carboxiloxane dendrimer that contains at least 3 silicon-bonded hydrogen atoms in each molecule, and(D) 0.1 to 10 weight parts organoperoxide.
