PAI

PAI (Polyamide-imide) is an imidized thermoplastic material, with a continuous use temperature range of up to 500° F (260° C).

Description

PAI (Polyamide-imide), also known as Duratron® or Torlon® is an imidized thermoplastic material, with a continuous use temperature range of up to 500° F (260° C). It is categorized as an extreme performance material, and offers high strength and wear resistance, and the ability to withstand harsh thermal, chemical, and stress conditions.

Offered in a variety of extruded and compression-molded grades and shapes, PAI is a versatile material ideal for a broad range of applications, including electrical applications. It can endure severe bearing and wear conditions while providing greater compressive strength and higher impact resistance than most advanced engineering plastics. PAI exhibits outstanding resistance to wear, creep, and chemicals – including strong acids and most organics – and is ideally suited for severe service environments.
