PTFE film: Various variants for the electrical industry

PTFE is a material with an impressive combination of properties. Foil is also made from PTFE. The PTFE film is thermally very hard-wearing and can be used at temperatures between -200 and +250 ° C. PTFE film is easy to clean and can be sterilized with commercially available agents.

We produce in our machining department CNC milled parts and CNC turned parts made from this material. In our stamping department, we manufacture flat gaskets for use in chemistry, vehicle, and mechanical engineering as well as in the food industry. Flat seals are used as flange seals, for seals in valves and shafts and as roof seals in construction. Also as the Insulating part, the Slot insulation and Cover slide is PTFE film in Electric motor construction used. We also manufacture feathered ribbons made of PTFE film for transformer construction.

Overview of PTFE foils:

  • PTFE film, virginal, full-width or cut to size

    Our delivery program includes PTFE foils in rolls with a thickness of 0.05 – 2 mm. The standard width is 1,200 mm, but we are also happy to offer you appropriate tapes, punched parts, cuts and special sizes

  • PTFE film, etched on one side, pretreated for gluing

    One-sided etching of the PTFE film is required for bonding the material.

  • PTFE film type SK, self-adhesive on one side with silicone adhesive

    (Assembly aid)

    We also supply PTFE foils with an adhesive layer on one side. These are available in strengths of 0.13; 0.25 and 0.50 mm. These are roll goods with a standard width of 1,000 mm. We are happy to offer ribbons, stamped parts, cuts and special sizes from this according to customer requirements.

  • PTFE coated glass fabric films in full width on a roll, like a cut or made up to conveyor belts.

    The PTFE foils consist of a PTFE-coated fabric tape made of glass fibers. This PTFE film we deliver in different thicknesses and types between 0.08 and 0.25 mm. Special types of foils are also available, for example in an antistatic or self-adhesive version. We are happy to offer ribbons, stamped parts, cuts, and special sizes according to customer requirements.

  • PTFE laminates

    We manufacture laminates from PTFE and other foils and sheet materials, which then have special property profiles.


From the project sketch to the finished series part made of PTFE film

As part of the product design, Dr. Dietrich Müller GmbH has many possibilities and ideas to achieve improved production processes and optimal product quality.

From the first tool-free sample production to series production, experienced application engineers and specialists are available for the implementation of punched parts made of PTFE.

In the area of ​​prototype production from PTFE, the most modern knife cutting machines and water jet cutting technology are available. In addition, the first samples can also be produced on the CNC machining centers. We do not cut PTFE on our laser cutting machines, as toxic fumes can develop that are harmful to health. These vapors also attack our laser cutting machines.

Stamped parts made of PTFE foil

In the area of ​​series production in the manufacture of punched parts from PTFE film, the most modern punching machines, rotary punching machines, eccentric presses and hand punching are used.

Cutting of tapes from PTFE foil

The cutting department is also equipped with the latest Kampf roll cutting machines and adhesive tape cutting machines from CMC Cevenini. That Cutting of PTFE foil Is no problem.
