Preparation and Preliminary Study on Irradiated and Thermally Treated Polypropylene (PP) - Styrene Butadiene Rubber (SBR) Composite
Keywords:Polypropylene, Styrene butadiene rubber, Tensile strength, Elastic modulus.
The tensile strength (TS) and elastic modulus (ES) of non-irradiated (thermally treated) and irradiated Polypropylene (PP) - styrene butadiene rubber (SBR) composites were studied. The content of SBR (mass %) on PP and radiation dose play an important role on tensile strength and modulus of elasticity of PP-SBR composites. Tensile strength (TS) decreased markedly on increasing the SBR content on PP and even on exposing to radiation. The elastic modulus (EM) of PP-SBR composite has a tendency to increase with radiation dose and aging time but decreases with SBR loading. The water uptakes increase with SBR loading which accelerate with aging.
Keywords: Polypropylene; Styrene butadiene rubber; Tensile strength; Elastic modulus.
