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 10 times more wear resistance than 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
