THEIC-modified polyester wire enamels are used as a basecoat on aluminum and copper wires and offer very good mechanical, electrical, chemical and thermal resistance. THEIC-polyesterimide wire enamels, which are highly heat-resistant, offer very good mechanical, electrical and chemical resistance.

Thermally Upgraded (Thermally Improved) Modified Polyester (TUE/M) wire enamels are a type of insulation coating used on magnet wires. They are designed to provide enhanced thermal properties compared to standard polyester enamels.

Here are some key features and specifications of TUE/M wire enamels:
Insulation Material: TUE/M wire enamels are typically based on modified polyester resin systems. The modification involves adding specific additives to enhance the thermal resistance of the enamel.

Thermal Class: TUE/M wire enamels are classified under a higher thermal class compared to standard polyester enamels. The thermal class rating represents the maximum temperature the wire enamel can withstand without significant degradation of its electrical and mechanical properties. TUE/M enamels typically have thermal class ratings of 155°C, 180°C, or higher.

Thermal Stability: The modified polyester resin system provides improved thermal stability, allowing the wire enamel to withstand higher operating temperatures. This makes TUE/M enamels suitable for applications where higher temperature resistance is required.

Electrical Insulation: TUE/M wire enamels provide effective electrical insulation, preventing short circuits and breakdowns between the conductor and other conductive elements. They exhibit good dielectric strength and insulation properties.

Compatibility: TUE/M wire enamels are compatible with various conductor materials, including copper and aluminum. They can be used in applications where these conductors are used.

Applications: TUE/M wire enamels find application in a range of electrical devices and equipment, including:

Motors and Generators: TUE/M enamels are used in the winding wires of electric motors, generators, and alternators, providing both electrical insulation and improved thermal resistance.

Transformers: TUE/M enamels can be used in the windings of transformers, including power transformers and distribution transformers, where higher thermal performance is required.

Coils and Inductors: These wire enamels are suitable for use in coils, inductors, solenoids, and other electromagnetic devices.

Automotive: TUE/M enamels are employed in various automotive applications, such as ignition coils and electric vehicle components, where higher temperature resistance is necessary.
