Torlon® 4275 LF

Product functions: Fuel Resistant, Acid Resistant, Mineral/Synthetic Oil Resistant, Dielectric Properties, Non Flammable, Flame Retardant, High Hardness, Low CLTE, Good Mold Release, Carbon Fibre Reinforcement, Glass Fibre Reinforcement, Good Thermal Stability, High Heat Resistant
Torlon® 4275 is a wear-resistant grade of polyamide-imide (PAI). This grade offers an excellent balance of mechanical properties and wear resistance. It offers high tensile strength and modulus with a low coefficient of friction and outstanding wear resistance at both high velocity and high pressure conditions.
Torlon® PAI has the highest strength and stiffness of any thermoplastic up to 275°C (525°F). It has outstanding resistance to wear, creep and chemicals.
Potential applications for Torlon® 4275 polyamide-imide include thrust washers, spline liners, valve seats, bushings, bearings, wear rings, cams and other applications requiring strength at high temperature and resistance to wear.
