Insulated wire
An object of the present invention is to provide an insulated wire which includes an insulating layer with a low relative permittivity and has excellent heat resistance and excellent abrasion resistance. The insulated wire of the present invention includes a conductor (A), and an insulating layer (B) formed on the periphery of the conductor (A), the insulating layer (B) is formed from a resin composition that contains a resin (I) with a relative permittivity of 3.0 to 4.0 and a fluororesin (II).
1. An insulated wire comprising
a conductor (A), and
an insulating layer (B) formed on the periphery of the conductor (A),
the insulating layer (B) is formed from a resin composition that contains a resin (I) with a relative permittivity of 3.0 to 4.0 and a fluororesin (II),
wherein the resin (I) is a polyarylene sulfide,
wherein the insulating layer (B) has a mass ratio (I):(II) of the resin (I) to the fluororesin (II) of 30:70 to 15:85,
wherein the fluororesin (II) is a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1):
CF 2 ═CF—Rf 1 (1)
wherein Rf 1 represents —CF 3 or —ORf 2 , and Rf 2 represents a C1-C5 perfluoroalkyl group, and
wherein the fluororesin (II) is formed from 80 to 99 mol % tetrafluoroethylene and 1 to 20 mol % perfluoroethylenic unsaturated compound represented by the formula (1).
2. The insulated wire according to claim 1 ,
wherein the fluororesin (II) is a copolymer of tetrafluoroethylene and at least one perfluoro monomer selected from the group consisting of perfluoro(alkyl vinyl ethers) and hexafluoropropyl ene.
3. The insulated wire according to claim 1 ,
wherein the fluororesin (II) is a copolymer of tetrafluoroethylene and perfluoro (alkyl vinyl ethers).
