High-performance electrical insulation Kapton film

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.
