Why use Formex™ film for electrical insulation?

Formex™ electrical insulation is used for:

  • Insulation barriers in power supplies
  • Transformer insulation
  • Separation of electronic components
  • Electrical boxes
  • Battery applications
  • Industrial equipment

Thanks to its high dielectric properties, Formex™ insulation film ensures electrical safety while simplifying industrial integration.

Compared to conventional polyester film :

  • The Formex™ film offers enhanced electrical insulation.
  • It is optimised to meet UL requirements
  • It offers greater mechanical strength in an insulated configuration

PET film remains a versatile solution, while Formex™ is specifically designed as a certifiable electrical insulating material.

Our teams will assist you in choosing between insulating polyester film and Formex™ according to your application.

What is Formex™?

Formex™ is a polypropylene electrical insulating material developed to replace more complex or costly solutions in electrical protection applications.

Formex™ polypropylene film combines:

  • Excellent dielectric strength
  • High mechanical resistance
  • Good temperature resistance
  • Resistance to humidity
  • Dimensional stability
  • Compliance

It is particularly suitable for applications requiring a certifiable and reliable insulating material.
