Title: POLYORGANOSILOXANE COMPOSITIONS VULCANISABLE BY HOT PROCESS USEFUL IN PARTICULAR FOR MAKING ELECTRIC WIRES OR CABLES
Abstract:
The invention concerns polyorganosiloxane compositions vulcanisable by hot process into silicone elastomers, useful in particular for making electric wires and cables displaying enhanced reaction to fire, containing: (a) at least a polyorganosiloxane polymer; (b) at least a reinforcing filler; (c) an organic peroxide; (d) mica; (e) zinc oxide; (f) optionally at least an additive normally used in polysiloxane compositions vulcanisable by hot process. Said compositions are characterised in that they further contain, as other indispensable ingredients: (g) platinum, a platinum compound and/or a platinum complex; (h) titanium oxide; (i) at least a packing filler; and (j) at least a mineral species belonging to the wollastonite group.
