Comparison of Physicomechanical Properties of NBR–PVC Blend Cured by Sulfur and Electron Beam

ABSTRACT: In this research, physicomechanical properties including tensile strength, elongation at break, hardness, resilience, and aging of acrylonitrile butadiene rubber–poly vinyl chloride (NBR–PVC) blend cured by sulfur and electron beam are investigated. The Taguchi method is employed in order to formulate the sulfur curing system. Electron beams in dose rates from 0 to 150 kGy are applied to cure NBR–PVC blends without sulfur curing system. Results show that the physicomechanical properties, except resilience, of NBR– PVC blend cured by the electron beam improved by 15 % compared with blends cured by the sulfur system
