Patent ID: 8729391

Claim:
A wire or cable comprising a conductor or wire core and a coating layer on the exterior of the conductor or wire core which is formed from a rubber or plastic composition containing a rubber or plastic and an inorganic filler, wherein the inorganic filler is the one which has been surface treated with an alkoxy group-containing organopolysiloxane having an unsaturated aliphatic group-containing group and a monovalent hydrocarbon group of 3 to 10 carbon atoms containing no aliphatic unsaturated bond obtained by partially cohydrolytic condensation or alkoxylation (when X is a halogen atom) following the partially cohydrolytic condensation of an organic functional group-containing silane represented by the following general formula (1): (R 1 )(R 2 )Si(X) 2 (1) wherein R 1 represents an unsaturated aliphatic group-containing group or a monovalent hydrocarbon group of 3 to 10 carbon atoms containing no aliphatic unsaturated bond, R 2 represents a monovalent hydrocarbon other than R 1 , and X represents a halogen atom or an alkoxy group of 1 to 4 carbon atoms, and/or its (partially) hydrolytic condensate, and an organic functional group-containing silane represented by the following general formula (2): (R 3 )Si(X) 3 (2) wherein R 3 represents an unsaturated aliphatic group-containing group or a monovalent hydrocarbon group of 3 to 10 carbon atoms containing no aliphatic unsaturated bond, and X represents a halogen atom or an alkoxy group of 1 to 4 carbon atoms, and/or its (partially) hydrolytic condensate, wherein the molar ratio (unsaturated group-containing group:alkoxy group) of the unsaturated aliphatic group-containing group to the alkoxy group in the alkoxy group-containing organopolysiloxane used for the surface treatment of the inorganic filler is at least 1, and the molar ratio (unsaturated group-containing group:monovalent hydrocarbon group) of the unsaturated aliphatic group-containing group to the monovalent hydrocarbon group of 3 to 10 carbon atoms containing no aliphatic unsaturated bond is at least 1.
