Torlon 4301 Stronger and Tougher than PEEK and polyimide from cryogenic to 500°F

Torlon 4301 is a high modulus polyamide-imide containing graphite and PTFE for improved wear resistance.  It is the general purpose wear grade of Torlon with an excellent balance of strength and impact resistance. It offers a wear rate that is 10% that of non-reinforced Torlon 4203 and has a CLTE that approaches that of many metals. 

 Torlon 4301 is ideal for:  

  • Bushings(highly loaded)
  • High temperature wear pads
  • Thrust washers
