Teonex® - PEN film with excellent properties
This polyethylene naphthalate (PEN) film is perfect for high-end applications due to its many superior properties. Teonex® films are ideal for use in automotive applications (traction motors, hermetic motors) as well as industrial applications.
Compared to PET polyester films, Teonex® has an increased property profile in every respect. The increased temperature resistance leads to the approval of the film in temperature class F (155 °C). According to UL, it has an electrical relative temperature index (RTI) of 180 °C and a mechanical RTI of 160 °C.
Further advantages of Teonex® are:
- extremely high dielectric strength
- high mechanical strength
- high-level stiffness
- low water absorption
- easy to laminate
- low oligomer extraction
The properties, dielectric dissipation factor and dielectric constant of PEN film are virtually constant over a wide temperature range and frequency range. Further technical data please find here.
