Thermal and Frictional Characteristic Comparisons of Friction Linings Made with Varying Elastomeric Modifiers

Elastomeric modifiers have been commonly used in friction lining compounds to provide resilience, stability of frictional characteristics, reduced wear and improved fade resistance as well as providing some level of noise and vibration dampening. Thermal and frictional characteristics according to SAE J2430 will be compared between friction linings made with a virgin powder of Styrene Butadiene Rubber (P-SBR), a powder of reclaimed Styrene Butadiene Rubber (Tire Scrap) and a highly defined morphology powder of Nitrile Butadiene Rubber (DM-NBR). Unique performance advantages of friction linings made with higher loading levels of DM-NBR powder and reduced copper content will also be discussed.
