Abstract :Waste tyres around the world are increased severely in the last century. The accumulation of waste tyre within poly dimethyl siloxane insert ignore into journalissuearticles values(silicone); and ethylene–propylene–diene monomer rubber insert ignore into journalissuearticles values(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.
