Wear properties of silica-filled SBR and three kinds of carbon black-filled SBRs were investigated. The wear volume of rubber was measured when rubber specimens were rubbed against metal gauze using a pin-on-cylinder type tribometer.<br>The coefficient of friction consists of adhesion component of friction, μA and hysteresis component of friction, μH. The adhesion component of friction is given by μA=A·s/W, where A is contact area, s is shear strength, W is applied load. It is thought that the wear volume depends on friction energy dissipated.<br>In this paper the wear volume per unit friction energy KA was compared with the energy density at break U. It is found that KA and 1/U showed linear correlation for the carbon black-filled SBRs, while the silica-filled SBR showed higher KA value compared to that of the carbon black-filled SBRs.
