Polyimide film non-adhesive high temperature resistant
Property profile of polyimide film
Polyimide films combine a special profile of properties. A very high temperature resistance, chemical resistance as well as electrical values allow polyimide film to be used in a wide range of applications.
Manufacturing processes for polyimide film
There are two manufacturing processes for polyimide film, which are essentially distinguished by the different cross-linking. A distinction is made between chemical and thermal cross-linking. This different cross-linking results in different technical values.
Applications for polyimide film
Chemically cross-linked polyimide films are used for the most demanding applications. Polyimide films produced in this manufacturing process are, for example, the Apical polyimide films of the company Kaneka as well as the Norton TH polyimide films of the company St. Gobain.
These chemically cross-linked polyimide films are used in traction machines, in laminates with Nomex, in the manufacture of printed circuit boards and in applications that require a material that is resistant to radioactivity. Insulating parts are made from this material.
Areas of application for Flexiso PI FI 16000 polyimide film
Flexiso PI FI 16000 is used in applications that require high temperature resistance and chemical resistance, but do not make the highest demands.
These are mainly adhesive tape applications or housing insulation. Insulating parts for various applications are also made from this material.
Polyimide film for fuel cells
Another field of application for polyimide films are fuel cells. The property profile of polyimide film is suitable for gaskets and as membrane frames in these applications.
Thickness range of polyimide films
As standard, polyimide films are available in thicknesses from 0.025 to 0.125 mm. Our product range also includes thinner and thicker polyimide films. Polyimide film in 125µ thickness is always available from stock, as are the other thicknesses. 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 of polyimide film. For example, thermally conductive polyimide films, electrically conductive polyimide films, corona resistant polyimide films and others are produced.
Laminates made from polyimide film
It is possible to produce laminates from the various polyimide films. Polyimide films are often bonded with Nomex to form NKN laminates, but there are also laminates with glass or with polyimide film.
Stampings, mouldings and insulating parts made from polyimide film
Punched parts, moulded parts and insulating parts can be made from the polyimide films mentioned. We also manufacture slot insulations, cover slides and phase insulations for electrical engineering from polyimide film. We also use polyimide film to manufacture feathered tapes for transformer construction.
Data sheets of polyimide films
The data sheets of the polyimide foils 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 the polyimide films
The polyimide films are UL approved. Due to our approval as UL recognised repackager the materials do not lose their UL-approval.
Sources of supply for polyimide film
Polyimide film or polyimide tapes can be purchased directly from us or from our dealers or distributors.
