A Study on the Mechanical and Thermal Properties of ENR Filled with Dual Fillers

Article Preview

Abstract:

The effects of dual fillers, carbon black (CB) and mineral filler mixture (MFM) in epoxidized natural rubber (ENR) compound using BR1600 internal mixer were investigated. In this study, the processability of the compound improved and the cure time decreased with partial replacement of CB with MFM. Results also showed that compound filled with partial replacement of 20 phr of CB with MFM exhibited comparable tensile strength value with compound filled with 50 phr CB as single filler. Nevertheless, based on Thermogravimetri analysis (TGA), ENR filled with 50 phr CB gave higher char yield which can ascribe to the better stability of the char layer formed.
