Abstract

A fluorine-containing elastomer covered electric wire includes a conductor, and a covering layer on a periphery of the conductor. The covering layer includes a composition including 100 parts by weight of a tetrafluoroethylene-propylene system copolymer and 0.1 to 10 parts by weight of a fatty acid amide.

Claims

1. A fluorine-containing elastomer covered electric wire, comprising:

a conductor; and

a covering layer on a periphery of the conductor,

wherein the covering layer comprises a composition comprising 100 parts by weight of a tetrafluoroethylene-propylene system copolymer and 0.1 to 10 parts by weight of a fatty acid amide.

2. The fluorine-containing elastomer covered electric wire according to claim 1, wherein the covering layer comprises a cross-linking structure.

3. The fluorine-containing elastomer covered electric wire according to claim 2, wherein the tetrafluoroethylene-propylene system copolymer comprises a mole ratio of tetrafluoroethylene to propylene in a range of 90/10 to 45/55.

4. A method for making a fluorine-containing elastomer covered electric wire, comprising:

forming on a periphery of a conductor a covering layer comprising a composition comprising 100 parts by weight of a tetrafluoroethylene-propylene system copolymer and 0.1 to 10 parts by weight of a fatty acid amide,

cross-linking the composition so as to form a cross-linking structure in the covering layer.

5. The method according to claim 4, wherein the cross-linking of the composition comprises a cross-linking by a cross-linking agent previously included in the composition, or a cross-linking by irradiating the composition with electron beam or ultraviolet rays.
