PEN film for electrical insulation

The PEN insulating film is used for:

  • Electric motor insulation
  • Transformers
  • Electronic modules
  • Battery components
  • Applications for Power and Mobility
  • Industrial equipment

Its high dielectric strength allows for reliable insulation in industrial environments.

The PEN film offers:

  • Best thermal outfit
  • Improved dimensional stability
  • More stable electrical performance

PET film remains more economical, whereas polyester PEN film is chosen when thermal constraints are higher.

Our experts will help you precisely size your solution.

What is the film PEN?

PEN (polyethylene naphthalate film) film is a technical polyester optimised to offer:

  • Better thermal resistance than PET
  • Excellent dielectric properties
  • Good dimensional stability
  • High mechanical resistance
