Property profile of polyimide film

Polyimide films combine a special profile of properties. A very high temperature resistance, chemical resistance and electrical values ​​allow polyimide film to be used in a wide range of applications.

Manufacturing process for polyimide film

There are two manufacturing processes for polyimide film, which are essentially differentiated by the different cross-linking. A distinction is made between chemical and thermal crosslinking. This different networking results in different technical values.

Application areas for polyimide film

Chemically cross-linked polyimide films are used for the highest requirements. Polyimide films that are produced in this manufacturing process are, for example, the Apical polyimide films from Kaneka and the Norton TH polyimide films from St. Gobain.

These chemically cross-linked polyimide films are used in traction machines, in laminates with Nomex, in circuit board production and in applications that require a material that is resistant to radioactivity. Insulating parts are made from this.

Areas of application of the polyimide film Flexiso PI FI 16000

The Flexiso PI FI 16000 is used in applications that require high temperature resistance and chemical resistance, but do not have the highest requirements.

These are mainly adhesive tape applications or housing insulation. This material is also used to manufacture insulating parts for various applications.

Polyimide film for fuel cells

Another area of ​​application for polyimide films is fuel cells. The profile of properties of the polyimide film is suitable for seals and as a membrane frame in these applications.

Range of thicknesses of the polyimide films

As a standard, polyimide films are available in thicknesses from 0.025 to 0.125 mm. Our delivery program also includes thinner and thicker polyimide films. Polyimide film in 125µ thickness is always available from stock, as are the other thicknesses. The product polyimide film is also available in 250µ.

Special types of polyimide film

In addition to the standard polyimide film, there is a whole range of special types made of polyimide film. Thus, thermally conductive polyimide films, electrically conductive polyimide films, corona-resistant polyimide films and others are produced.

Polyimide film laminates

It is possible to manufacture laminates from the various polyimide films. Polyimide foils are often bonded with Nomex to form NKN laminates; But there are also laminates with glass or with a polyimide film.

Stamped parts, molded parts and insulating parts made of polyimide film

Stamped parts, molded parts and insulating parts can be manufactured from the polyimide films mentioned. We also manufacture slot insulation from polyimide film, Cover slide, and phase insulation for electrical engineering. We also manufacture from polyimide film feathered ribbons for transformer construction.

Data sheets of the polyimide films

The data sheets of the polyimide films can be downloaded by clicking on the PDF symbol in the table. If a data sheet is not available, it can be requested by email.

UL approval of polyimide foils

The polyimide films are UL-approved. Thanks to our approval as a UL recognized repackager, the materials do not lose their UL approval.

Where to buy polyimide film

Polyimide film or Polyimide adhesive tapes can be obtained directly from us or from our dealers or distributors.

NORTON TH Polyimidfolie

Norton TH is also a polyimide film that has a special profile of properties:

  • Insulation class R (up to 220 ° C)
  • Norton® TH is a polymide film
  • Use at extremely low temperatures down to – 265 ° C and at high temperatures up to + 400 ° C
  • Permanent temperature resistance of +220 ° C
  • Highest flammability classification according to UL-94 V-0
  • excellent chemical resistance;
  • no known organic solvents
