Insulated wire, cable and molded article

Abstract

An insulated wire includes an outermost layer including a resin composition including a fluorine-containing elastomer. A ratio of C═O bond to C—C bond (C═O/C—C) on a surface of the outermost layer is not less than 0.5. The resin composition further includes a tetrafluoroethylene-propylene copolymer and an ethylene-tetrafluoroethylene copolymer as the entire base polymer or a portion of the base polymer at a mass ratio ((of the tetrafluoroethylene-propylene copolymer) to (the ethylene-tetrafluoroethylene copolymer)) in a range of 100:0 to 60:40. The resin composition further includes 5 to 60 parts by mass of calcium carbonate and/or silica as an inorganic filler with respect to 100 parts by mass of the base polymer. The resin composition is cross-linked.

What is claimed is: 
     
         1 . An insulated wire, comprising an outermost layer comprising a resin composition comprising a fluorine-containing elastomer, wherein a ratio of C═O bond to C—C bond (C═O/C—C) on a surface of the outermost layer is not less than 0.5,
 wherein the resin composition further comprises a tetrafluoroethylene-propylene copolymer and an ethylene-tetrafluoroethylene copolymer as the entire base polymer or a portion of the base polymer at a mass ratio ((of the tetrafluoroethylene-propylene copolymer) to (the ethylene-tetrafluoroethylene copolymer)) in a range of 100:0 to 60:40, 
 wherein the resin composition further comprises 5 to 60 parts by mass of calcium carbonate and/or silica as an inorganic filler with respect to 100 parts by mass of the base polymer, and 
 wherein the resin composition is cross-linked. 
 
     
     
         2 . The insulated wire according to  claim 1 , wherein the outermost layer is treated by atmospheric-pressure plasma. 
     
     
         3 . A molded article, comprising:
 the insulated wire according to  claim 1 ; and   a molding material on an outer periphery of the insulated wire.   
     
     
         4 . A cable, comprising an outermost layer comprising a resin composition comprising a fluorine-containing elastomer,
 wherein a ratio of C═O bond to C—C bond (C═O/C—C) on a surface of the outermost layer is not less than 0.5,   wherein the resin composition further comprises a tetrafluoroethylene-propylene copolymer and an ethylene-tetrafluoroethylene copolymer as the entire base polymer or a portion of the base polymer at a mass ratio ((of the tetrafluoroethylene-propylene copolymer) to (the ethylene-tetrafluoroethylene copolymer)) in a range of 100:0 to 60:40,   wherein the resin composition further comprises 5 to 60 parts by mass of calcium carbonate and/or silica as an inorganic filler with respect to 100 parts by mass of the base polymer, and   wherein the resin composition is cross-linked.   
     
     
         5 . The cable according to  claim 4 , wherein the outermost layer is treated by atmospheric-pressure plasma. 
     
     
         6 . A molded article, comprising:
 the cable according to  claim 4 ; and   a molding material on an outer periphery of the cable.   
     
     
         7 . A molded article, comprising:
 the insulated wire according to  claim 2 ; and   a molding material on an outer periphery of the insulated wire.   
     
     
         8 . A molded article, comprising:
 the cable according to  claim 5 ; and   a molding material on an outer periphery of the cable.
