Abstract (en)

[origin: WO2004064081A1] The invention concerns polyorganosiloxane compositions heat-vulcanizable into silicone elastomers, useful in particular for making electric wires or cables with high fire resistance satisfying current standards, containing: a) at least one polyorganosiloxane polymer; b) at least one reinforcing filler; c) an organic peroxide; d) mica; e) zinc oxide; f) optionally at least one additive normally used in the preparation of heat-vulcanizable polyorganosiloxane compositions; g) platinum, a platinum compound and/or a platinum complex; h) titanium oxide; i) at least one packing filler; and j) optionally at least one mineral species belonging to the wollastonite group. Said compositions are characterized in that the packing fillers i) consist in aluminium hydroxide powders AI(OH)3 surface treated with an organoalkoxysiloxane and/or an organosilazane and/or an organosiloxane oligomer bearing OH and/or alkoxy radicals.
