Abstract
The present disclosure provides an electric wire having excellent smoothness, appearance, and storage stability. The electric wire includes a core wire and a coating layer covering the core wire. The coating layer contains a fluorine-free resin and a fluorine-containing crystalline polymer. The fluorine-free resin includes at least one selected from the group consisting of polyamide resins, polyolefin resins, and polyvinyl chloride resin. The fluorine-containing crystalline polymer represents 0.5 to 4.0 mass % relative to the fluorine-free resin.
Claims3
A power cable comprising
- a core wire and a coating layer covering the core wire,
- wherein the power cable is 10 to 1000 V power cable,
- the core wire is a core wire with a diameter large than AWG54,
- the coating layer consists of a fluorine-free resin, a fluorine-containing crystalline polymer, and optionally an additive selected from the group consisting of a heat-resistance stabilizer, an antioxidant, a flame retardant, and a pigment,
- the fluorine-free resin including polyamide 6,
- the fluorine-containing crystalline polymer including at least one selected from the group consisting of polytetrafluoroethylene (PTFE), tetrafluoroethylene (TFE)/perfluoro (alkyl vinyl ether) (PAVE) copolymers (PFA), TFE/hexafluoropropylene (HFP) copolymers (FEP), ethylene (Et)/TFE copolymers (ETFE), Et/TFE/HFP copolymers (EFEP), and polyvinylidene fluoride (PVdF),
- the fluorine-containing crystalline polymer has an average particle size of 2.0 to 10.0 μm,
- the fluorine-containing crystalline polymer has a melting point of 140° C. to 300° C., and
- the amount of the fluorine-containing crystalline polymer is 0.5 to 4.0 mass % relative to the fluorine-free resin.
