PEN - Harsh Environment Film

Recognized as the first polyethylene naphthalate (PEN) film globally, Teonex® PEN film is the product of choice for harsh environment applications. Manufactured by Teijin DuPont Films™, Teonex® PEN fills the performance gap between polyester films and high performance polyimide films.  Tekra can make a recommendation for Teonex® PEN film based on your specific performance requirements. Our sampling process involves sampling and product data review.

Teonex® PEN film has many superior properties such as strength, heat resistance, anti-hydrolysis, dimensional stability and low oligomer extraction. Teonex® can be used for flexible printed circuits, solar and PV cells, and automotive applications. PEN film is also used in electronic components such as capacitors, electric insulation, battery, and for optical end uses. Because of these performance characteristics, PEN film has the potential to replace other engineering films, such as polyimide, with added cost performance. Teonex® also has good handling properties (similar to polyester film).

Teonex® PEN films should be considered a specialty product offering. They are manufactured in gauges from 1 mil to 10 mil. Based on volume, stocking programs can be established to lessen the impact of product availability and lead times. Three of the more commonly referenced PEN film types are:

  • Teonex® Q51 > standard
  • Teonex® Q83 > low shrink
  • Teonex® Q65FA > high transparency, stabilized
