Copper Clutch Facing

● The main materials of this series consist of ordinary medium-alkali (alkali-free) glass fiber, hybrid fibers, 4 -7 pieces of copper wire of composite cloth, imported styrene-butadiene rubber 1502, high decomposition phenolic resin and organic friction modifier.
● The products adopt the traditional rubber impregnation technology. Due to the high copper content, the mechanical strength and wear resistance are greatly improved. It can be applied to various types of cars, especially heavy truck. The clutch working life can be increased greatly also.
● The main varieties include: FST109, FST189, FST706, FST806, etc.
