The Study of the Development of Natural Rubber Blends using Different Types of Polymers and Fillers on the Mechanical and Chemical Properties of the Vulcanizates

Abstract

The mechanical properties, natural rubber (NR) blends were studied in various ratio; 100:0, 85:15, 70:30 and55:45.Two different types of filler were tested: carbon black and carbon Nano. It was found that, the increasing carbon black and carbon Nano compositions improve the tensile strength of the NR/PE,NR/PS blends. It was found that the incorporation of( PE , PS) in the blend compositions leads to the decrease in degree of swelling, Mechanical properties of the vulcanizates were examined. As expected, when the (PE, PS) were increased, The range of ratios evaluated are NR(70) /PE (30) , NR(85) /PS (15)  blends resulted in better tensile properties.The effect of chemical and oil resistance on rubber blends were studied.
