Polyamide-imide [PAI]

With proven versatility across a wide range of applications, polyamide-imide (PAI) shapes are available in both extruded and compression-molded grades. This advanced material delivers outstanding mechanical performance and dimensional stability, making it ideal for demanding high-temperature applications.

Grades

● Duratron® T4203 PAI
● Duratron® T4301 PAI
● Duratron® T5530 PAI

  • Very high maximum allowable service temperature in air [250 °C continuously]
  • Excellent retention of mechanical strength, stiffness and creep resistance over a wide temperature range
  • Excellent wear & frictional behavior [particularly Duratron® T4301 & T4501 PAI]
  • Superb dimensional stability up to 250 °C
  • Inherent low flammability
  • Very good UV-resistance
  • Exceptional resistance against high energy radiation [gamma- and X-rays]
  • In applications subject to severe wear, it is preferred for on-lubricated bearings, seals, bearing cages, and piston compressor components.
  • It is also suitable for precision parts used in the electronics and semiconductor industries.
  • PAI components, which absorb moisture relatively easily, should be kept dry before installation if intended for high-temperature service or produced to tight tolerances.
  • Rapid exposure to temperatures above 200 °C can cause deformation due to thermal shock.
