Other Products - Rumal Rubber Crumb
Decreased hardness and increased flexibility
Typical percentages used per application are:
Commercial Vehicle Linings: 2-10% (w/w)
Passenger Car Disc Pads: 1-5 % (w/w)
Commercial Vehicle Disc Pads: 1-3 % (w/w).
Impact particle size
• Coarser particles will create more flexibility and a lower hardness.
• Finer particles will generate a better wear performance.
