The purpose of this study is to find the suitability of a crosslinkable processing aid, trans-polyoctenylene (TOR) on general purpose rubber based filled compounds for application in thick rubber products. Objective is to have better processability as well as improvement in vulcanizate properties using TOR. Thus to investigate its effect as processing aid, rheological behaviour of TOR filled Styrene butadiene rubber (SBR) compounds has been studied in a capillary rheometer. Two types of carbon black were used. All compounds show pseudoplastic behaviour and obey Power-law equation in the shear rate range studied. True viscosity decreases marginally at 60°C and increases little at 100°C with addition of TOR. Die swell (index) decreases with incorporation of TOR, a probable mechanism has been suggested. Maximum recoverable deformation (vm) has been correlated with die swell (α). Principal normal stress difference (N1) decreases with increase in TOR which is explained through mechanistic theory of particle-particle interaction. Incorporation of TOR in the system lowers activation energy of flow. Study concludes with selection of TOR dose. |
