SILICONE RUBBER COMPOSITION FOR INSULATING MATERIAL OF HIGH VOLTAGE ELECTRICITY AND INSULATOR

摘要

PROBLEM TO BE SOLVED: To obtain a silicone rubber composition having an excellent insulating properties for high voltage electricity, keeping the properties of silicone rubber even when highly filled with aluminum hydroxide. ;SOLUTION: This silicone rubber composition for insulating material of high voltage electricity comprises (A) 100 pts.wt. of an addition reaction cure type organopolysiloxane composition, (B) 30 to 400 pts.wt. of aluminum hydroxide which has the surface treated with an organosirazane practically excluding an aliphatic unsaturated group or organosilazane or their partial hydrolyzate having 0.01 to 2 wt.%. of carbons adhered on the surface, per 100 pts.wt. of (A).;COPYRIGHT: (C)1999,JPO
