The cure and physical properties of EPDM foam containing ground rubber and carbon black as filler were studied. The cure time reduced with the addition of filler. This result means reducing the operation time. In case of ground rubber was used, blowing ratio, tensile strength, and elongation were decreased rapidly at above 30 phr. On the other hand, in case of carbon black, they showed similar physical properties until 70 phr was used limited to 30 phr to make a good foam, which should be due to low interfacial interaction between EPDM and ground rubber. All the EPDM foams showed excellent thermal stability.
