This study investigated the influences of stearamide on the tensile modulus and strength of silica-loaded styrene-butadiene rubber (SBR). The SBR was filled with precipitated silica reinforcing filler at a settled dose (thirty phr) and the stearamide was compounded into the silica-filled SBR with range doses from two to eight phr. The influences of stearamide incorporation on the tensile moduli i.e. M300 and M100, tensile strength and also breaking elongation of silica-filled SBR were studied. It was revealed that the stearamide caused pronounced affection in tensile properties of the SBR. The stearamide increased tensile strength and modulus up to a six phr of dose. The improvement in tensile moduli and strength was because of the role of stearamide as the extra plasticizing agent for the silica-filled SBR. The oily property of stearamide improved the silica dispersion and crosslinks level, respectively.
