Kapton® MT Polyimide Film

Kapton® MT Polyimide Film is a thermally conductive, electrically insulating polyimide film designed for advanced heat dissipation in compact, high-power electronic assemblies. Unlike standard polyimide films, Kapton® MT offers more than triple the thermal conductivity (~0.45 W/m·K), allowing efficient heat transfer without compromising insulation integrity. It is used across power electronics, EV battery modules, aerospace avionics, and thermal interface layers in sensors and LED systems. The film’s stable dielectric behavior across a wide temperature range (−269 °C to +400 °C) makes it ideal for thermal bridges and heat spreaders in multilayer PCBs and power control units. Research demonstrates its superiority in thermal management versus conventional Kapton, enabling long-term stability in extreme conditions. Its ability to combine thermal control with mechanical resilience and electrical insulation continues to support innovation in energy systems, miniaturized avionics, and medical electronics.
