Studies on effect of titanate coupling agents on the mechanical properties of clay and talc filled styrene butadiene rubber

Abstract

679-683Effect of titanate coupling agent on clay and talc has been studied with polybutadiene as a matrix. Tensile properties were measured on a computerized UTM using ASTM procedure. Comparison of properties of composites filled with treated and untreated fillers established that treatment of fillers imparts better reinforcing properties. The properties under consideration were tensile strength, modulus (100% & 400%), Young’s modulus, hardness, etc. Improvement in properties for clay and talc respectively were as follows: Tensile strength, 14, 19; Modulus (400%), 140, 90%; and Young’s modulus, 275, 25%.</b
