TTP128 has a structure of highly conductive fibers designed to provide outstanding thermal capability, good wear resistance and µ-V characteristics. The use of porous carbonaceous materials improves the stability of the torque curve over a wide range of temperatures and pressures. TTP128 offers a low static to dynamic coefficient of friction for enhanced engagement characteristics, excellent energy capability, low noise and vibration, with good wear resistance.
