Effect of Reclaim Rubber Loading on the Mechanical Properties of SBR Composites

Ahmed M Ajam, Sameer Hassan Al-Nesrawy and Mohammed Al-Maamori

This article explores the possibility of using mix of reclaim rubber as reinforcement in styrenebutadiene rubber (SBR). Mix of reclaim rubber used in this research to enhancement some of the mechanical properties of SBR as additives or fillers. Six different compound was prepared from SBR (100 pphr) and loading level from Reclaim rubber (0, 50, 100, 150, 200, 250) pphr in series while the hardness, tensile strength, tear résistance, elongation, elastic modulus and specific gravity have been studied in this research. We found that some of these properties are increasing with the increment of mix of reclaim rubber loading, such as tensile strength, elongation, tear resistance, specific gravity from other hand hardness, elastic modulus, were decreased with increment reclaim rubber loading %.
