摘要：
A curable silicone wire and cable coating composition with improved flame resistance at heat flux rates of 50 to 90 kW/m2, made by mixing ingredients comprises: (A) 30 to 90 weight percent of a heat-curable non-halogenated organosiloxane polymer, containing at least 2 alkenyl groups per molecule, (B) 1 to 65 weight percent of a reinforcing silica filler, based on the total composition, (C) 5 to 70 weight percent wollastonite having an average particle size of 2 to 30 &mgr;m, based on the total composition, and (D) curing component sufficient to cure the composition.
