Electrically conductive silicone rubber compositions.

摘要

Cured electrically conductive silicone rubber products exhibiting bleed-out of a silicone oil at a controlled rate are prepared from compositions containing carbon black and a curable polyorganosiloxane wherein 90 mol % of the silicon-bonded hydrocarbon groups are methyl. The silicon oil is a liquid polyorganosiloxane containing at least 1 mol %, based on the total number of hydrocarbon radicals present in said silicone oil, of silicon-bonded halogenated hydrocarbon radicals and the silicone oil is incompatible with the cured silicone rubber product.
