Films can be used for a variety of applications. The Dr. Dietrich Müller GmbH insulating sleeves.

Flexible electrical insulation materials can be used for a variety of applications. From the flexible electrical insulation materials offered Polyimidfolie, Mylar, and Nomexwraps the Dr. Dietrich Müller GmbH insulating sleeves.

These foils are also processed as a laminate, so that two- or three-layer caps and sleeves are created.

4 different versions of the insulating sleeves

These spiral-wound insulating hoses are offered in different designs:

The four different versions are the shrinking, one-sided closed insulating cap, the non-shrinking, one-sided closed insulating cap, the shrinking, open insulating tube and the non-shrinking, open insulating tube.

Caps, sleeves and hoses can also be made from the other technical foils offered. In particular, closed caps made of thermally conductive polyimide film have already been implemented.

In addition, the Dr. Dietrich Müller GmbH insulating sleeves made of Tecfilm PEI TC 00421 in the color black. Sleeves made of Tecfilm PEI TC 00421 were manufactured in cameras for optical purposes.

Insulating caps made of battery separator foil

The Dr. Dietrich Müller GmbH also manufactures spiral-wound sleeves from various battery separator foils.

Applications of the insulating sleeves

The spirally wound foils are generally used for the electrical insulation of wire connections and thermal sensors in electric motors, generators and transformers. Most of the time, the insulating sleeves protect the internal wire connection from mechanical stress. Another function is electrical insulation.
