Electrical insulating enamels are usually made of thermosetting resins diluted in suitable solvents, which can be enameled on magnetic wires. PEI‐based enamel is one of the most important insulating enamels in electrical engineering. The characteristics of various PEI based wires are quite different depending on the final use. Using special additives, it is possible to produce optimized PEI versions with improved characteristics. Special applications are possible by introducing pigments or conductive materials in the formulation. Thermoplastic PEI are also obtainable. This review gives an overview of the fascinating world of PEI, from discovery up to the latest developments.
