Zusammenfassung:To an addition-curable silicone rubber composition comprising (A) an organopolysiloxane having at least two alkenyl groups, (B) an organohydrogenpolysiloxane having at least two SiH groups, (C) reinforcing silica, and (D) a platinum catalyst, a flame retardant combination of (E) a triazole compound and (F) an isocyanate compound is added. The composition cures into a silicone rubber which exerts excellent flame retardancy without compromising physical properties of the silicone rubber base.
