Thermotech 125

TTP125 is a non-asbestos cellulose fibre friction material reinforced with a high volume of graphite. This is a high strength material providing a very stable coefficient of friction and good thermal conductivity.

  • High heat stability
  • Smooth engagement characteristics
  • Excellent energy capability
  • Good wear resistance
