Kapton® is a thin polyimide film developed by DuPont. Birk has developed etched foil heaters using this polyimide material as the insulating layer for use in a number of applications. Kapton® polyimide heaters have an extremely thin profile and many other properties suitable for heating solutions. These heaters find applications in diverse industries for uniform and focused heating. They offer various benefits such as rapid heat up and cool down times. Due to their thin profile, they are ideal for heating small compact objects with simple or complex shapes, and are designed to work in harsh industrial environments. Our Kapton® polyimide heaters can operate even in high-vacuum environments.

Heating requirements depend on the application, making customization essential to achieve optimal performance. This is where Birk specializes—we can customize our Kapton® polyimide flexible heaters in various shapes and sizes as well as watt densities to suit the exact application requirements. Birk’s heaters can incorporate multiple heating zones and embedded sensors, which can be utilized to ensure extremely uniform heat distribution, in some cases down to +/- 0.1°C. These Kapton® polyimide heating elements can be immediately integrated into assemblies or systems in industries. Depending on your application needs, Birk can permanently bond these heaters to heat sinks in order to produce superior heat transfer. Birk Manufacturing is one of the leading Kapton® polyimide heater manufacturers in the world, and it offers turnkey heating solutions which help cut down costs and time. Our thin polyimide flexible heaters undergo thorough testing and inspection before being shipped out of our facility.

Birk is committed to offering the best products and services to all clients. We have a technically sound and resourceful team of engineers who can design fully custom Kapton® polyimide heater assemblies as per customer requirements. We invest significantly in research and innovation as well as our product quality, and our certifications are a testimony to this effort.

The following are technical specifications and capabilities for our custom Kapton® polyimide heaters:

Birk uses many different types of Kapton® materials for these heaters along with three bonding systems, which include FEP Teflon® adhesive, acrylic adhesive, and all-polyimide solutions.
