SynTherm® – Insulating Materials Teonex® Q51

Teonex® Q51 is a flexible, slightly cloudy, biaxially oriented polyethylenenaphthalate (PEN) film.

Compared to PET polyester film, Teonex® Q51 has optimum properties in every respect.

The increased temperature resistance results in film approval in thermal class F (155 °C). It has a electrical relative temperature index (RTI) of 180 °C and a mechanical RTI of 160 °C according to UL.

Further advantages of Teonex® Q51 are:

  • extremely high dielectric strength
  • very good mechanical strength
  • high-level of stiffnes
  • low water absorption
  • easy to laminate
