Abstract
Magnet wire including extruded insulation formed from a blend of 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 at least three different polymeric materials. A first polymeric material, such as polyetheretherketone, may have a thermal index above 250° C. Second and third polymeric materials, such as polyphenylsulfone and polyethersulfone, may have lower thermal indexes.
