ABSTRACT:
A flame-retardant silicone rubber composition is prepared by admixing a base compound of a dimethylpolysiloxane gum and a siliceous filler with a combination of a platinum compound and an organosilicon compound having at least one nitrogen-containing organic group and at least one aliphatically unsaturated group in a molecule in such a proportion that the molar ratio of nitrogen to platinum is within a specified range. The effect of flame retardancy exhibited by the composition is so reliable and constant that the effect can be obtained regardless of the type of the peroxide curing agent and the curing behavior of the composition is never affected by the formulation of the flame retardant agent.
