PAI (Torlon®)

PAI (polyamide-imide) (Torlon®) is a high strength plastic with the highest strength and stiffness of any plastic up to 275°C (525°F). It has outstanding resistance to wear, creep, and chemicals, including strong acids and most organic chemicals, and is ideally suited for severe service environments. Torlon is typically used to make aircraft hardware and fasteners, mechanical and structural components, transmission and powertrain components, as well as coatings, composites, and additives. It may be injection molded but, like most thermoset plastics, it must be post-cured in an oven. Its relatively complicated processing makes this material expensive, stock shapes in particular.
