Stronger focus on polyimide film

Dr. Dietrich Müller GmbH will focus even more strongly on polyimide films in the future. Here, the thickness spectrum and the variety of variants will be increased.

Dr. Dietrich Müller GmbH, a leading supplier of electrical insulation materials, thermal conductivity products, gaskets and technical films, has made a comprehensive expansion of its polyimide film n product range.

Larger thickness range of polyimide films

Polyimide films, which were previously available as standard in a thickness range of 12.5 – 125 µ, have been used due to this limitation in thickness due to their flexibility in the insulation of wires, conductors, cables, windings, motor slots, magnetic coils, transformers and capacitors. Special types are used in the insulation of highly heat-resistant wires, cables and flat cables as well as in the application as masking tapes.

Further strengths are now available for applications where the stiffness of the material, low moisture absorption, high dielectric strength and a V0 flammability rating are important.

Dr. D. Müller GmbH offers polyimide films under the brand name Flexiso PI FI 16000 in thicknesses of 0.150, 0.180, 0.200, 0.230 and 0.250 mm in addition to the known thicknesses. In addition, it is now also possible to obtain customer-specific films up to a thickness of 0.50 mm.

Dr. Dietrich Müller GmbH mentions housing insulation of electrical and electronic devices as well as slot insulation and deck slides in electric motors as areas of application, especially also for drives of electric vehicles in which polyester film is not sufficient due to the temperature resistance of 130°C. Another field of application are insulating parts for batteries. Housings of lithium-ion batteries must be lined with polyimide film for electrical insulation and fire protection.

Other special types

In addition to expanding the range of products in the thickness range, Dr. Dietrich Müller GmbH has also added other special types to its product range.

With the polyimide film Flexiso BW FI 16035, Dr. Dietrich Müller GmbH presents a thermally conductive polyimide film as an alternative to established products on the market. This film is used in electronic devices for cooling power modules and in the production of printed circuits. Dr. D. Müller GmbH supplies Flexiso BW FI 16035 with a thickness of 0.05 mm for a newly developed electronic system for a vehicle brake.

The polyimide film Flexiso CR FI 16055 is a corona resistant polyimide film, which is especially used for the insulation of profile conductors and cables – especially in electrically highly utilized systems.

Both films are available in adhesive and non-adhesive versions.

Transparent polyimide film

The company from Ahlhorn will soon be able to supply transparent polyimide films, which can be used in particular for applications in the field of displays. New foldable displays are predestined for the use of this film.

Further processing of polyimide films

Dr. D. Müller GmbH supplies the new polyimide films in cut rolls, as punched and formed parts or also as wide goods. Prototypes can also be produced on the company’s cutting plotters or laser cutting machines.

It is also possible to make the material fully or partially adhesive. This is where the Ahlhorn-based company uses its SP 61321 transfer adhesive.
