Silicone rubber composition having flame-retardant and electrical insulating properties

摘要

A silicone rubber composition is disclosed comprising(A) polyorganosiloxane described by average formula R_aSiO_(4-a)/2, where R denotes substituted and unsubstituted monovalent hydrocarbon groups and a is a number from 1.95 to 2.05 and having at least 2 silicon-bonded alkenyl groups in each molecule;(B) silica filler;(C) the reaction mixture of(a) a platinum compoundand(b) an organosilicon compound described by general formula where R¹, R², and R³ represent C₁ to C₁₀ monovalent hydrocarbon groups and a is 1, 2, or 3;(D) curing agent,and optionally(E) a triazole compound.
