A new concept is introduced in this study, suggesting the role played by ZnO crystal sulfur crosslinking polymers, particularly, rubber blends of EPDM-CTS. The study conducted a polymer blend ethylene propylene diene terpolymer (EPDM) and cyclic tetrasulfide (CTS). CTS reactive low molecular weight polymer, which can act as donor. It proposed that occurs at surface crystals. reaction site creat...
