What to Know About Kapton Film Molding

What to Know About Kapton Film Molding

Micro-Tronics is proud to offer niche services like Kapton film molding from our ITAR Registered,  ISO 9001:2015 and AS9100D-certified shop.

Kapton film molding refers to using heat and pressure to shape Kapton®, a thin polyamide film developed by Dupont, into customized 3D parts. 

We use a proprietary process involving special tooling and molds (all manufactured in-house here at MTI!) to form the thin Kapton into precise shapes. We’ve fine-tuned this process over 30 years of experience with Kapton film molding to ensure the material isn’t damaged and its critical properties are preserved.

Kapton: Properties, Applications, and Types


Kapton polyimide film is suitable for a wide range of industries and applications due to its thermal, electrical, and mechanical properties. The material is an excellent electrical insulator. With remarkable temperature and chemical resistance, Kapton operates well in demanding environments. 

Kapton has excellent temperature properties, as it has the highest UL94 flammability rating: V-0. Its temperature resistance allows for continuous service capabilities ranging from -452 degrees Fahrenheit to 464 degrees Fahrenheit (-269 degrees Celsius to 240 degrees Celsius) and intermittent service up to 752 degrees Fahrenheit (400 degrees Celsius). The materials’s exceptional chemical resistance prevents static buildup and discharge. 


Kapton is commonly used in applications such as seals, pneumatic actuators, and bearings. The full list of applications is quite extensive, so feel free to reach out if you have questions about your application. 


At Micro-Tronics, we use Kapton HN, which is typically used for wire insulation, conductors, cables, motor windings, solenoids, transformers, and capacitors. While Kapton HN is our go-to,  we can obtain the type of Kapton polyimide film you need for your part’s application.
