Teonex® PEN film has many superior properties such as strength, heat resistance, anti-hydrolysis, dimensional stability, and low oligomer extraction. These attributes provide performance improvements over polyester PET while also having cost advantages over highly engineered films like polyimides. Similar to other polyester films, Teonex® also has good dielectric properties, chemical resistance, and handling properties.

Teonex® PEN films are ideal for electrical insulation applications in high temperature environments, such as automotive batteries and fuel cells, solar cells, flat flexible cables, flexible printed circuitry, motors, capacitors, and transformers.
