Thermotech 127

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
