Allex magnet wire consists of an aromatic polyimide film that combines not only thermal stability in the class 240, but unmatched chemical and burnout resistances. Allex is used in encapsulated windings and hermetically sealed components because of the excellent chemical resistance and low weight loss characteristics at elevated temperatures. - Allex is resistant to unusual environments such as radiation and can be used in many electronic devices found in aerospace, nuclear and other such applications.
