Abstrakt: In this research work, stearamide was used as a rubber additive to improve the tensile behaviours or properties i.e., breaking elongation, the strength of tensile and moduli of the styrene-butadiene rubber (SBR)/carbon black (CB) compounds. The stearamide was made in a laboratory by performing a chemical reaction between stearic acid and urea. Since the stearic acid is based on a fraction of palm oil, the stearamide can be considered as a (semi) sustainable material. The lab-synthesized stearamide was added into the SBR/CB compounds at five different compositions (i.e., 2, 4, 6 and 8 phr.), CB and other chemicals of rubber were compounded with SBR using a two-roll mill. Those compounds were vulcanized using a semi-efficient formulation at 150 oC using a typical rheometer. Based on the tensile properties of the vulcanized SBR/CB with no/with stearamide which was measured using a typical tensometer; it was found that the presence of stearamide in the SBR/CB compounds improved not only the tensile strength but also the elongation at break compared to the SBR/CB compound with no stearamide. The strength improvement of the SBR/CB compounds presumably was due to the function of the stearamide which level up the degree of the CB filler homogeneity inside the SBR compounds.
