| Abstract | The effects of defatted rice bran (DRB) as a filler for natural rubber vulcanisate on its cure characteristics, mechanical properties and morphology were investigated. The properties of the DRB-filled vulcanisate were also compared with clayfilled and CaCO3-filled vulcanisates. At similar loading level (50 parts per hundred of rubber), DRB-filled vulcanisate gave the shortest cure time. Clay-filled vulcanisate showed highest tensile and tear strength followed by DRB-filled vulcanisate. However, CaCO3-filled vulcanisate gave highest rebound resilience while DRB-filled vulcanisate exhibited highest modulus, hardness and abrasion resistance. Scanning electron micrographs revealed that the morphology of clay-filled vulcanisate was more homogenous than that of DRB-filled and CaCO3-filled vulcanisates. According to these observations, DRB can potentially be used as a cheap and more environment-friendly natural filler when an improvement in mechanical properties was not so critical. |
