Virgin EPDM and recycled EPDM fine particles that is crushed by high temperature shear-crushing technique from recycled EPDM were blended with the various mixing ratio to rubber blends. The cure characteristics and physical properties of these blended rubber compounding were investigated with the contents of recycled EPDM and physical properties of these blends for heat and antifreeze and compression set were also measured. Recycled EPDM materials prepared by high temperature shear-crushing technique were blended to virgin EPDM with the range of 0~50 phr. The testing results of physical properties indicated that the rubber blends of recycled EPDM with 25~35 phr turned out to be the best compounding showing good dispersibility, heat resistance and anti-freezer resistance and inexpensive in price.
