PAI film: properties, applications and processing

PAI film: properties, applications and processing

What is PAI film?

PAI (polyamide-imide) is a high-performance thermoplastic material that offers excellent mechanical, thermal and chemical properties. PAI film is particularly known for its high temperature resistance, low coefficients of friction and exceptional wear resistance. These properties make PAI film preferred in demanding applications where maximum performance under extreme conditions is required.

Properties of PAI film

PAI film is characterized by a number of outstanding physical and chemical properties that make it an indispensable material in industry:

  • Temperature resistance: PAI films retain their mechanical properties even at very high temperatures, typically up to 275°C. For short periods, they can even withstand temperatures up to 300°C.
  • High mechanical strength: The film has high strength, rigidity and dimensional stability. This makes it ideal for applications where extreme mechanical stress occurs.
  • Low friction coefficient: PAI offers excellent sliding properties and is therefore ideally suited for applications where low wear and friction reduction are important.
  • Chemical resistance: PAI films are resistant to a wide range of chemicals, including oils, greases and various solvents.
  • Good electrical insulating properties: The films provide excellent electrical insulation, making them a preferred material in the electronics industry.

These exceptional properties make PAI film ideal for use in critical environments where conventional materials quickly reach their limits.

Production of PAI film

The production of PAI film requires precise and complex production technology that is tailored to the demanding material. PAI is produced in a multi-stage polymerization process in which the polymer is created by chemical reactions between aromatics and isocyanates. This process results in a polymer that is extruded or cast into thin films.

To ensure consistent quality and performance, strict control of the manufacturing process is crucial. Dr. Dietrich Müller GmbH works with state-of-the-art manufacturing methods that ensure that PAI film is produced in consistent quality and thickness.
