Kapton® MT

Thermal conductivity properties ideal for controlling and managing heat in electronic assemblies

DuPont™ Kapton® MT polyimide film is a homogeneous film possessing 3x the thermal conductivity and cut through strength of standard Kapton® HN.

Kapton® MT offers an excellent combination of electrical properties, thermal conductivity and mechanical toughness for its use in electronic and automotive applications.

Kapton® MT has higher modulus than HN; this offers improved strength to the final product. As all Kapton® films, MT retains its properties for extended storage periods in original packaging at temperatures between 4–29°C (40–85°F).

Applications include:

  • Insulation pads (heat sink)
  • Heater circuits
  • Power supplies
  • Ceramic board replacement
