ARTICLE INFO Ethylene Propylene Diene Monomer (EPDM) rubber emerges as a dominant elastomer for major engineering applications such as automotive (sealing, bushing, serpentine belts), construction (roofing, dilatation joints) and electric/electronic (insulators). Due to friction between the EPDM bushing and the mating surfaces, it loses material resulting in noiseand failure. Fillers like Carbon black enhance the mechanical properties such as the abrasion resistance or the fatigue life and

It can be operated for solid friction without lubrication and for boundary lubrication with liquid lubricants.By using different % of Carbon black in EPDM, we may find the most effective composition to reduce specific wear rate of bushings.
