Physical properties of magnet wire enamel films

There is much technical data on the properties and behavior of magnet wire enamels on their conductors, that is, as magnet wire. However, the behavior of the enamel resin is influenced by the presence of and its adherence to the conductor. We have determined certain basic physical properties of unsupported magnet wire enamel films. These results are useful in better understanding the behavior of the corresponding magnet wires. Table I gives the enamels investigated by type and source.
