Kapton Heating Foil: High-Performance Flexible Heating Solutions

Overview of Kapton Heating Foil

Kapton heating foil, also referred to as polyimide film heater, is a highly reliable and efficient flexible heating element used in a wide range of demanding industrial applications. Made from DuPont™ Kapton® polyimide film, this advanced heating solution provides precise and uniform heat distribution in compact spaces while withstanding harsh environmental conditions.

Kapton heating foils are especially valued for their lightweight structure, thin profile, and excellent thermal and electrical insulation properties. These characteristics make them ideal for use in industries where space, weight, and reliability are critical—such as aerospace, medical devices, automotive systems, and electronics.

What is Kapton Heating Foil?

Kapton heating foil is created by etching a metal heating circuit, typically made of copper-nickel alloy or stainless steel, and sandwiching it between layers of Kapton polyimide film. The result is an ultra-thin, flexible heater that delivers consistent thermal performance across its surface.

The heater operates efficiently across a wide temperature range, from as low as -60°C to up to +300°C, maintaining its structural integrity and heating capability even under extreme conditions. Its low outgassing properties also make it ideal for vacuum environments such as outer space or clean rooms.

Key Features of Kapton Heating Foil

1. Ultra-Thin and Lightweight Design

Kapton foil heaters are incredibly thin—typically between 0.13 mm and 0.3 mm—making them perfect for applications with tight space constraints. Despite their minimal thickness, they are robust and capable of delivering significant power density.

2. Fast Thermal Response

Thanks to their low thermal mass, Kapton heaters heat up and cool down rapidly. This quick thermal response is essential for applications that demand precise temperature regulation and energy efficiency.

3. Uniform Heat Distribution

The etched-foil design allows for even heat dispersion over the entire surface of the heater, minimizing hotspots and enhancing performance.

4. Chemical and Moisture Resistance

Kapton is highly resistant to chemicals, solvents, oils, and moisture, making these heaters suitable for both harsh industrial environments and sensitive electronics.

5. Wide Operating Temperature Range

Kapton heating foil can operate effectively in a range from -200°C to +260°C, allowing use in cryogenic as well as high-temperature applications.

6. Electrical Stability

These heaters offer high dielectric strength and excellent electrical insulation, reducing the risk of short circuits and electrical failures.
