PAI Machining

A Guide to PAI CNC Machined Parts: Properties, Applications and Design Considerations

What is PAI?

PAI (Polyamide-imide) is a high performance amorphous thermoplastic which is often used in place of metal components where there are weight restrictions. 

PAI is considered the highest performing thermoplastic. It is available in a number of grades (such as carbon-fibre reinforced, glass-fibre reinforced, PTFE-filled, graphite-filled, unfilled, wear resistant, high strength, low friction) with varying characteristics.

Main Attributes of PAI:

  • High service temperature in air (up to around 260°C continuously)
  • Good UV resistance
  • Excellent dimensional stability
  • Low coefficient of linear thermal expansion
  • High creep resistance
  • Yellow to brown colour
  • Excellent chemical resistance (except strong alkali, oxidising acids & nitrogen containing solvents)
  • Excellent electrical properties
  • High cost
  • Flame resistant
  • High impact strength
  • Can be bonded
  • Low moisture absorption
