Torlon® 4301

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® 4301 is a wear-resistant grade of polyamide-imide (PAI) resin. It has a good balance of mechanical properties and wear resistance. It offers high flexural and compressive strength 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® 4301 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. 
Injection molding grade:
Low Flow: Torlon® 4301-LF
Extrustion Grades:
High Flow: Torlon® 4301-EXT
