Is there black Kapton or black polyimide film?

Kapton or polyimide film is also available in black. There is black polyimide film which is equipped with extra properties.

Black Kapton is deliverable ex works of the company Dr D. Mueller GmbH.

Die-cut- , formed- and insulating parts can be manufactured of the black polyimide film.

Black Kapton can also be delivered self-adhesive.

What is polymide film?

Polyimide film is an electric insulating material with excellent properties. Polyimide [Abbreviation: PI] is a thermoplastic plastic for high temperature applications.

Polyimide film is very dimensionally stable, has a very high dielectric strength and is HF qualified as non-adhesive film. In many cases polyimide film is manufactured self-adhesive.

Is polyimide film resistant against x-rays?

Kapton has a good long-term resistance against x-rays.

Can Kapton also be used as x-ray window?

For the production of x-rays polyimide films often are used as multifunctional, stable and low-cost materials for x-ray windows. Requirements for this are thermal stability and high transmittance for x-ray light.
Of course we manufacture these x-ray windows in small demands as well as in single pieces.

If additional a high absorption and reflexion for light of the visual area is required, mainly beryllium is used.

Which CTI value has Kapton?

Kapton has a CTI of 4.

Is Kapton suitable for the usage in vacuum?


Kapton is suitable for the usage in vacuum.

Can polyimide film also used as membrane?

Polyimide films are used as selective permeable membrane in the reverse osmosis – e.g. in the dialysis or in the seawater desalination. Suchlike membranes can be manufactured from our company as serial parts, in small demands or as single pieces.

It is also possible to equip single parts self-adhesive.

What is about the delivery time of the polyimide film?

Polyimide film of the different brands is mostly available ex works.

Where can I buy polyimide film?

Polyimide film can be bought at Dr D. Mueller. Small demands or regular manufacturing needs, all that customers can buy at our company.

Which polyimide film is qualified to meet the requirements of the UL 746 C?

The solution is named Kapton 200XP919. At this special Kapton model a 12.5µm thick covering of PFA is placed on the 25µm thick Kapton film.
Then the CTI value 1 is met and it fulfils the requirements of UL 746C.

In which thicknesses is polyimide film available?

Kapton is available in the thicknesses 0.0125 mm, 0.025 mm, 0.05 mm, 0.075 mm and 0.125 mm.

Flexiso PI 16000 is also available in the thickness of 0.225 mm.

Laminates can also be manufactured of the polyimide films.


Can Kapton film also be used as fixation of strain gauges?

Kapton films can be used as fixation of strain gauges. In this case the silicone adhesive covered with polyimide film is used.

What are the application areas of polyimide film?

Polyimide film is used in the following areas:
Covering of conductor plates
Covering of connection plug boards (Goldkante)
Usage in brazing processes in the electro industry
Usage in the high temperature area
Covering at powder coating
