Torlon 4275 Stronger and Tougher than PEEK and polyimide from cryogenic to 500°F

Torlon 4275 is a high modulus polyamide-imide containing graphite and PTFE for improved wear resistance.  It is an enhanced wear grade of Torlon with improved properties over 4301 especially at high velocities. Its wear rate is lower than 4301 under most PV conditions.

Torlon 4275 is ideal for:  

  • High speed bushings
  • Bearing cages
  • Piston rings
