Duratron® PAI

With its versatile performance capabilities and proven use in a broad range of applications, Duratron® polyamide-imide (PAI) shapes are offered in extruded and compression moulded grades. For high temperature applications, this advanced material offers an excellent combination of mechanical performance and dimensional stability.

This polyamide-imide is the highest performing, melt processable plastic. It has superior resistance to elevated temperatures. It can perform under severe stress conditions at continuous temperatures to 260 °C (500 °F). Parts machined from Duratron stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics.

Duratron® PAI’s extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range. It is an amorphous material with a Tg (glass transition temperature) of 280 °C (537 °F).

• 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.
• Superb dimensional stability up to 260°C.
• Excelent friction and wear behavior (especially Duratron® T4301 and T4501 PAI).
• Very good UV-resistance.
• Exceptional resistance against high energy radiation (gamma- and X-rays).
• Inherent low flammability.
