Kapton® polyimide film possesses a unique combination
of properties. The ability of Kapton® to maintain its
excellent
physical, electrical and mechanical properties over a wide temperature range
has opened new design and application areas for plastic films.
Kapton® is extensively used for aerospace, printed circuit and traction motor applications, operating up to 400°C. It has proved to be an indispensable material for advanced applications. The primary types of Kapton® are:
- Kapton® HN - Used for the majority of applications, where its properties are required over a wide temperature range. The standard sizes are shown below.
- Kapton® FN - Where heat sealabfility is required. Kapton® is combined with Teflon® FEP resin. It is commonly used for lapping of copper conductors in electric motors and aerospace wires.

Short Roll Service: Kapton® HN is normally supplied in standard rolls, however Katco also provides short rolls from 5 linear metres long x 610mm wide.
Additionally, we supply slit width rolls, die-cut and punched components as well as adhesive coated Kapton®.
Other grades of Kapton® may be obtained by special
request.
