Abstract
An insulated wire, containing a conductor and an insulating film (A) provided in contact with the conductor, in which the insulating film (A) contains polyaryletherketone, the polyaryletherketone has an exothermic peak at the range of 290 to 330° C. in a differential scanning calorimetry when the polyaryletherketone is cooled at a temperature falling rate of 10° C./min from a temperature equal to or higher than the melting temperature of the polyaryletherketone, and the half width of the exothermic peak is 6° C. or more.
Claims13
An insulated wire, comprising:
- a conductor;
- and
- an insulating film (A) provided in contact with the conductor;
- wherein the insulating film (A) contains polyaryletherketone;
- wherein the polyaryletherketone has an exothermic peak at the range of 290 to 330° C. in a differential scanning calorimetry when the polyaryletherketone is cooled at a temperature falling rate of 10° C./min from a temperature equal to or higher than the melting temperature of the polyaryletherketone;
- and wherein the half width of the exothermic peak is 6° C. or more.
A method of producing an insulated wire, comprising a step of forming an insulating film by extrusion-covering a resin containing a polyaryletherketone on the outer periphery of a conductor,
- wherein the polyaryletherketone has an exothermic peak at the range of 290 to 330° C. in a differential scanning calorimetry when the polyaryletherketone is cooled at a temperature falling rate of 10° C./min from a temperature equal to or higher than the melting temperature of the polyaryletherketone;
- and
- wherein the half width of the exothermic peak is 6° C. or more.
A resin for an insulating film, comprising polyaryletherketone, wherein the polyaryletherketone has an exothermic peak at the range of 290 to 330° C. in a differential scanning calorimetry when the polyaryletherketone is cooled at a temperature falling rate of 10° C./min from a temperature equal to or higher than the melting temperature of the polyaryletherketone;
- and wherein the half width of the exothermic peak is 6° C. or more.
