Influence of Vulcanization System on the Mechanical Properties of CCTO/ENR50 Composite

Abstract

A study on vulcanization systems consist of conventional (CV), semi-efficient (SEV) and efficient (EV) was carried out by fabricating the CCTO/ENR50 composites. The rubber compound was mixed in internal mixer at 60°C and 60 rpm rotor speed for 13 min. Then, followed by hot pressing at 160°C. The effect of the vulcanization system of the composites was closely monitored on mechanical properties (stress versus strain, tensile strength, elongation at break and hardness. As a result, the CCTO/ENR50 composites with the SEV system exhibit higher modulus strength, which is related to the stiffness of the composite. Hence, it reduced the elongation at break (%) from 591 (CV system) to 495% (SEV system). It also gives high tensile strength, 5.47 MPa, and 47.74 Shore A in hardness compared to other vulcanization systems.
