    摘要: A method for producing a conductive liquid silicone rubber composition having an excellent storage stability and suitable for molding a conductive silicone rubber article with an arbitrary speed of curing and with good reproducibility of arbitrarily selected hardness and volume resistivity. The method comprises mixing component (A) which is a mixture of a conductive filler with a liquid diorganopolysiloxane having two or more silicon-bonded alkenyl groups in one molecule, component (B) which is a mixture of a conductive filler with a liquid diorganopolysiloxane having two or more silicon-bonded alkenyl groups in one molecule and a volume resistivity different from that of (A), component (C) a platinum-based catalyst; and component (D) which is a cross-linker that comprises an organopolysiloxane having two or more silicon-bonded hydrogen atoms in one molecule.
