Abstract
Magnet wire with thermoplastic insulation that reduces copper poisoning may include a conductor, and at least one layer of thermoplastic insulation formed around the conductor. Additionally, the thermoplastic insulation may include a matrix polymeric material and one or more additives incorporated into the matrix polymeric material, wherein the one or more additives mitigate copper poisoning, such as migration of copper ions from the conductor into the insulation layer, decomposition of the insulation layer as a result of copper ions, and/or oxidation on the surface of the conductor.
