Abstract

Waste tyres around the world are increased severely in the last century. The accumulation of waste tyre within poly dimethyl siloxane (silicone) and ethylene–propylene–diene monomer rubber (EPDM) rubbers were examined. The moving die rheometer were used for the kinetic analysis of the samples. The MDR results showed that the silicone sample that has 5% waste tyre content has the better rheological results. Kinetic study examination of both EPDM and silicone rubber were done according to non-linear curve fitting model. The fitting model were conducted as Kamal-Sourour Model. In addition, the fitted model was corrected with fourth order Runge-Kutta model. Moreover, activation energy of both samples were calculated from Arrhenius plot for both rubbers. For EPDM case, it was found 99 kJ/mole and 66 kJ/mole for mth order and nth order, respectively. For silicone case, it was found to 87 kJ/mole for nth order. The results were hearting enough to pursue the accumulation of waste tyre on other rubbers.
