PAI (Torlon®) sheets

PAI – Polyamidimid – is commonly known as Torlon®. It is a semi crystalline thermoplastic that combines strength with dimensional stability in a way that makes it ideal for components exposed to high temperatures and great pressure. Torlon is especially used for hard pressed technical parts that, on top of being exposed to great pressure, works under high temperatures, such as pistons, piston rings, valves etc. The material good wear resistance as well as thermal stability makes it ideal for motor- and machine parts as well as electrical components. 


  • Preserves long term mechanical strength and stiffness in broad temperature spectrum
  • Extremely high dimensional stability in up to 250°C
  • Extremely good wear and tear capabilities - especially Torlon 4301 PAI
  • Outstanding UV-resisters
  • Extremely resistant to radiation - gamma and x-ray
  • Low combustion
  • High stiffness
  • High exhaustion strength
  • Can be used with steam
  • Can be used with many aggressive chemicals

There are an additional 3 Torlon qualities available through Vink Plastics; Torlon 4203 PAI (yellow/ochre), Torlon 4301 PAI (black) and Torlon 5530 PAI (black). Contact us for further information.
