Kapton® MT+

High performance thermally conductive polyimide film

DuPont™ Kapton® MT+ polyimide film is a homogeneous film possessing over 5x the thermal conductivity of standard Kapton® HN, while retaining the strong mechanical and dielectric properties you expect from a polyimide film.

Kapton® MT+ offers the highest thermal conductivity of any polyimide film on the market and offers excellent breakdown voltage, mechanical resilience, and flexibility to make it an ideal substrate to incorporate into an electrically isolating thermal solution for your electronic or automotive application.

Performance:

  • Thermal conductivity of 0.8 W/m·K
  • Dielectric barrier of 5 kV/mil

Applications:

  • Lithium-ion Battery cell/pouch wrap
  • Electric motor slot liner
  • Heater circuits
  • Power supplies
  • Ceramic board replacement

Benefits:

  • 5 °C decrease in operating temperature of E-motor as component of
    NKN slot liner solution
  • 30% decrease in heater power draw to achieve steady-state temperature

Thermal modeling reveals how Kapton® MT+ polyimide film efficiently conducts heat to eliminate hot spot formation.
