HOT VULCANIZABLE ELASTOMERIC ORGANOPOLYSILOXANE COMPOSITION WITH REVERSION RESISTANCE AND IMPROVED OIL RESISTANCE.

摘要

The present invention relates to a silicone rubber with resistance to reversion and resistance to improved oils. The rubber according to the invention is obtained by hot vulcanization of an elastomeric organopolysiloxane composition formed by mixing A. of a diorganopolysiloxane gum, B. of a reinforcing and / or semi-reinforcing filler, D. d 'an organic peroxide, E. of a hydroxide or an alkaline earth oxide and G. of an organosilicon compound comprising, connected to the silicon atom, at least one acroyloxyalkyle or methacroyloxyalkyle group. BR/ The rubbers according to the invention can in particular be used as seals in contact with hot oils in closed systems.
