The effects of cross-linking systems on the morphology and mechanical properties of EPDM/PVC composites were studied. Three cross-linking systems, sulphur, dicumyl peroxide and a mixture consisting of sulphur and peroxide were used for vulcanization. DCP vulcanized system possesses higher torque than sulphur cross-linked ones. Composite with 7.5 phr PVC samples prepared exhibited optimum mechanical properties. The amount of cross-linking agent is also found to affect the mechanical properties. The morphology has been studied for complementing the observations related to the above mentioned characteristics.
