Teijin® Teonex® PEN Films

Teijin® Teonex® PEN film is a biaxial oriented polyethylene naphthalate (PEN) product. Manufactured by Teijin DuPont Films™, Teonex® PEN fills the performance gap between durable polyester films and high performance polyimide films. Tekra can make a recommendation for Teonex PEN film based on your specific performance requirements. This process involves sampling and product data review. We carry a limited offering of sample sheets for this selection process.

Teonex® PEN film has many superior properties such as strength, heat resistance, anti-hydrolysis, dimensional stability and low oligomer extraction. For those performance reasons, Teonex® 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 are manufactured in gauges ranging from 1 mil to 10 mil.   

Applications suitable for Teonex® PEN include virtually any stringent condition with exposure to extreme heat or harsh chemicals; or for those applications where exceptional barrier performance is required. Teonex® films are perfect for value-added applications in flexible printed circuits, labels, laminates, optical display and release.

Teonex® PEN films should be considered a specialty product offering. Product is 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 produced PEN film types are:

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