TF1700 is a high-performance material containing a significant percentage of Kevlar (aramid fiber) with metallic content. TF1700 virtually eliminates clutch slippage with a high torque capacity that avoids uncontrollable glazing. Additionally, TF1700 exhibits extraordinary wear life properties and has a high friction coefficient. When given a mating surface, clutch flywheel, brake rotor, or brake drum, it will dramatically outlast organic friction wear performance. TF1700 is completely non-abrasive against mating surfaces, promotes smooth engagement, resists very high surface pressures at the brake interface, and is an effective alternative for sintered materials since it handles high energy inputs in both dry and oil-immersed applications. TF1700 is available in sheets and in finished custom shapes and sizes, with thicknesses as low as 0.5mm.
