Kapton® MT Polyimide Film

Industrial Applications

Kapton® MT is specified wherever a thermal management film must also provide reliable electrical insulation, replacing ceramic and silicone pads in demanding power and precision electronics applications:

✦ Power Electronics & Semiconductor Modules

Applied as the thermally conductive dielectric layer in insulated metal substrates (IMS), power module base plates, and IGBT/SiC module assemblies. Kapton® MT allows efficient heat extraction from power dies to heatsinks while maintaining the electrical isolation voltages required in high-voltage inverters, motor drives, and industrial power supplies.

✦ Electric Vehicles & Hybrid Powertrains

Used in EV battery module thermal management as an electrically isolating, thermally conductive inter-cell film and bus bar insulator. Kapton® MT dissipates heat from battery cells during charge and discharge cycles while providing the voltage isolation between cells and structural components required by EV battery safety standards.

✦ LED Lighting & Solid-State Lighting Systems

Specified as the dielectric and thermal interface layer in high-power LED modules, where junction temperature control is directly linked to lumen output, colour point stability, and LED lifetime. Kapton® MT enables compact LED thermal management solutions that combine the flexibility needed for curved lighting arrays with effective heat removal from the LED chip to the aluminium substrate.

✦ Aerospace Avionics & Satellite Electronics

Applied in high-power avionics modules, radar transmit-receive (T/R) assemblies, and satellite power conditioning units, where the film's thermal conductivity, extreme temperature range, radiation tolerance, and low outgassing combine to address thermal management challenges in weight- and volume-constrained aerospace platforms.

✦ Medical Imaging & High-Performance Electronics

Used as a thermally conductive dielectric in MRI gradient amplifier modules, CT scanner power stages, and high-power diagnostic electronics, where thermal management and electrical isolation must be simultaneously optimized in a compact package. Note: Kapton® MT is not suitable for applications involving permanent implantation in the human body or contact with internal body fluids or tissues.

✦ Industrial & High-Temperature Processing Equipment

Applied in motor slot liners, transformer coil insulation, and Class H electrical insulation systems in industrial machinery, where Kapton® MT's elevated thermal conductivity reduces coil hot-spot temperatures, directly extending winding insulation life and equipment uptime in continuously loaded industrial motors and generators.

✦ Flexible Thermal Interface Films

Used as a flexible, die-cuttable alternative to ceramic and graphite thermal interface materials in portable electronics, power converters, and telecom equipment. Kapton® MT can be precisely cut to component footprints, compressed between surfaces for intimate thermal contact, and integrated into multilayer thermal stacks without the brittleness that limits rigid TIM solutions.
