PI / Polyimide Machining

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

What is PI?

Polyimides (PI or often referred to as the brand name Vespel®) are a family of some of the most heat and fire resistant polymers in existence. Low wear rates combined with the ability to work under unlubricated conditions and high pV-rates makes it the ideal material for challenging friction and wear applications, extending lifetime and reducing maintenance costs. 

There are many different grades of PI/Polyimide, all with varying characteristics. A comparison of the technical properties can be found in the tab below.

Main Attributes of PI:

  • High strength
  • Outstanding wear resistance
  • High dimensional stability, even up to 260°C
  • Long term thermal stability 300°C
  • Excellent thermal and electrical insulation
  • Good machinability
  • Flame retardant
  • Creep resistant
  • Good chemical resistance
  • Resistance to high energy radiation
  • Excellent machinability
