The non-shrink insulating conduit made of Mylar® A is used for robust insulation in electrical applications. It is also available with an electrically conductive surface coating for special applications. It is wound very precisely from polyester film. It has a high dielectric strength and mechanical impact resistance and is also suitable for demanding applications. It is mainly used as secondary insulation in windings of lacquer-impregnated and open electric motors.
