The tensile properties and morphology analysis of recycled mattress filled natural rubber compounds

Abstract

The tensile properties and morphology analysis of Recycled Mattress (rMat) filled Standard Malaysian Rubber (SMR L) and Epoxidized Natural Rubber (ENR 50) was successfully studied. The both compounds were prepared by two roll mill at five different compositions of rMat (5, 15, 25, 35 and 50 phr). Two different ranges of rMat particles i.e, (300-700 micron) fine, and (3-5 cm) coarse size were used. Results show that fine sizes of rMat filled both SMR L and ENR 50 recorded better tensile performance including tensile strength, rigidity at 100% of elongation and elongation at break, respectively. Ultimately, scanning electron microscopy (SEM) micrographs of tensile fracture surface was also obtained to further clarify the failure mechanism experienced by both compounds.
