Thermotech 127

Industrial Parts  /  TTP127 Carbon Friction Paper

TTP127 has a structure of highly conductive fibers designed to provide outstanding thermal capability. The use of porous carbonaceous materials improves the stability of the torque curve over a wide range of temperatures and pressures.

  • Low ratio of static to dynamic coefficient of friction for enhanced engagement characteristics
  • Smooth engagement
  • Excellent energy capability
  • Good wear resistance

TYPICAL APPLICATIONS Differential & Wheel Brakes, Torque Converter Clutches, Transmissions

MATING MATERIAL Steel, Cast Steel, Grey Cast Iron
Surface Finish < 0.5μm Ra (20μ")
