The processability of TESPD coupled silica-black-solution SBR with zinc fatly acids (EF and ZB) in an internal mixer and extruder was investigated. The processability, rheological property, and vulcanization property of their composite were measured as a function of storage conditions including time and humidity and as a function of mixing sequence (1P and 2P). Processing through a single screw extruder processing additive, zinc fatty acid, added compounds exhibited lower pressure build up than without-additive compound (Control) and their viscosities were lower than the Control. The EF-2P and the ZB-2P compounds exhibited lower pressure build up than the EF-1P and the ZB-1P ones, respectively. The Mooney viscosities of both the dry and the humid exposed ones increased as the storage time increased and the viscosities of the humid exposed compounds exhibited slightly higher than the dry ones. The cure times of the humid exposed compounds were shorter than that of the dry ones, and as the storage time increases, the cure time of the dry ones were varied depending on mixing sequence; however that of the humid exposed ones were decreased. The torque rises (M-H - M-L) of the humid exposed compounds were higher than that of the dry ones as the storage time increases, and while the torque rises of the dry compounds tend to remain constant that of the humid exposed ones increased. Processing additive added compounds (EF-1P EF-2P ZB-1P and ZB-2P) exhibited lower modulus and longer cure time than the Control.
