EPDM polymers are also used in blends with natural rubber (NR) and styrene butadiene rubber (SBR) for tire sidewall applications as a non-staining antiozonant. Table 4 shows some typical formulations of tire sidewalls and the physical properties.
The antiozonant (6PPD) and antioxidant (TMQ) and the rest of the curatives: zinc oxide (ZnO), stearic acid (SA), sulfur (S), tetramethylthiuram disulfide (TMTD), and N-cyclohexyl 2-benzothiazole sulfonamide (CZ) were all obtained from Infochems Company Ltd.
Vulkanox antioxidant and antiozonant products protect against oxygen, heat, and unoriented crack formulation (crazing), and are also effective, to some extent, against fatigue.
