Polyamide-imide (Torlon®)
PAI offers the highest strength and stiffness of any thermoplastic. With exceptional wear resistance and thermal stability up to 275°C, it's the ultimate material for extreme mechanical and thermal demands.
PAI (sold under the brand name Torlon®) represents the pinnacle of thermoplastic performance. It combines the exceptional mechanical properties of polyimides with the processing advantages of thermoplastics.
PAI maintains its strength and stiffness at temperatures where most other plastics fail, making it ideal for metal replacement in extreme environments. It offers outstanding wear and friction properties, especially in unlubricated applications.
