Optimization of vulcanisation system on the rheological and thermal properties of ENR-50 filled CCTO composite

Abstract

The vulcanization system of conventional (CV), semi-efficient (SEV) and efficient (EV) were used to investigate the rheology and thermal properties of ENR-50 filled CCTO composite. The composites were successfully fabricated via the melt mixing method in an internal mixer at 60°C and 60 rpm rotor speed for 10 min. Then, the rubber-filler interaction and rheology properties of the composites were investigated using a rubber processing analyzer (RPA) before the compounding process occurs at 160°C. As a result, the CV system expresses an excellent rubber-filler interaction. The observation for the thermal degradation showed that the EV system has the most outstanding thermal stability due to the monosulphidic bond in the network structure. The degradation starts at 85°C and 260°C for EV and EV-C, respectively.
