Kapton® Film for high-performance electrical insulation

Kapton® electrical insulation is used for:

  • High-temperature electric motor insulation
  • Windings and coils
  • Lithium-ion batteries
  • Energy storage systems
  • Electronic power modules
  • Railway applications and electric mobility

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

Kapton® high-temperature film is recommended when:

  • The temperature is exceeding the limits of the PET film
  • Thermal cycling is common
  • The environment is chemically aggressive.
  • Dimensional stability is critical

It is widely used in demanding industrial environments where reliability is strategic.

Why choose Kapton® polyimide film?

Kapton® polyimide film is designed for applications where standard materials (PET, PP) reach their limits.

Key properties :

  • Resistance to high temperatures (> 250°C depending on grade)
  • Excellent dielectric properties
  • Exceptional dimensional stability
  • High chemical resistance
  • Radiation resistance
  • Good mechanical performance

Kapton® insulation film is particularly suited to environments with high thermal and electrical stress.
