15 properties of polyimide film developers should know

Polyimide films are used in electrical engineering/electronics because of their heat resistance, low outgassing, radiation resistance, and insulating properties in the form of light brownish, semi-transparent foils applied. High continuous use temperatures of up to 230 ° C and briefly up to 400 ° C are possible.

The following 15 properties of polyimide film should be known to developers when considering the use of Polyimide film employ:

  • Temperature resistance: can be used briefly from -269 ° C to +400 ° C.
  • Permanent temperature resistance: exists up to +230 ° C.
  • Flammability: is hardly inflammable, self-extinguishing and only starts to char at 800 ° C.
  • Melting point: has no melting point.
  • Chemical resistance: offers a high level of chemical resistance; an organic solvent is not yet known.
  • Radiation resistance: has a high resistance to radioactive radiation.
  • Outgassing: low outgassing
  • no creeping: does not tend to flow under pressure and temperature loads
  • Deep-drawing ability: there is the possibility of producing deep-drawn parts
  • oatability: can be coated with almost all adhesive and coating systems
  • Processability: can be cut and punched very well
  • Partial discharge resistance: shows resistance to corona discharges (special type)
  • Thermal conductivity: is thermally conductive up to 0.8 W / mK (special type)
  • Thickness range: possible in thicknesses as film from 0.0075 to 0.50 mm
  • Color options: amber, black, white and transparent


From the project sketch to the finished series part Polyimide film

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

The implementation of Die-cut parts made from polyimide film experienced application engineers and specialists in production are available.

In the area of ​​prototype production, the most modern laser cutting machines, knife cutting machines and water jet cutting technology are available. In addition, the first samples can also be produced at the CNC machining centers.

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

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