If inorganic compounds are added to the polymers it has been observed that the mechanical properties are improved. This may be due to the individual properties of compounds and their phases present. Particle size, length/ diameter ratio and structure of the filler material have great influence on the polymer properties. In the current research 5 different rubber compound were prepared by using (SBR 1502) type of Styrene Butadiene rubber in level and each recipe reinforced with Titanium Dioxide (TiO2 ) at constant ratio (60) pphr ( part per hundred ), Stearic Acid (S.A) at variable ratio (20,40,60,80 and 100) pphr The physical properties such as Tensile ,Elongation , Young Modulus and Compression were Studied . The result show that the hardness, Fatigue, Compression, wear, increase with loading level of (S.A). But the Tensile and Elongation that increase with excited ratio of (S.A) and decrease in another Value at 100 %.

Keywords: Stearic Acid, Rubber compounds etc.
