VH-03 is suitable for clutch facings with similar friction

VH-03
VH-03 is suitable for clutch facings with similar friction properties but with a higher stiffness, smooth
behavior and very high temperature resistance. VH-03 is a woven material with glass fiber and is
reinforced with copper. This clutch facing performs with very stable coefficient and resists temperature
with a minimum wear.
