Abstract
Magnet wire included extruded insulation formed from a blend of two or more different polymeric materials is described. A magnet wire may include a conductor and insulation formed around the conductor. The insulation may include at least one layer of extruded insulation formed from a blend of a first polymeric material and a second polymeric material different than the first polymeric material. The first polymeric material may include one of polyetheretherketone, polyaryletherketone, polyetherketoneketone, polyphenylsulfone, polyphenylene sulfide, or polybenzimidazole. The second polymeric material may include one of polyphenylsulfone, polyetherimide, polyethersulfone, polyphenylene sulfide, polycarbonate, or polyester.
Claims21
