In this proposed work, Natural Rubber (NR) and Ethylene Propylene Diene Monomer (EPDM) are blended using Graphical method in 50:50 ratio. The blends are characterized by electrical characteristics like surface resistivity, arc resistance and mechanical properties such as comparative tracking index, elongation at break and tensile strength as per standard ASTM and IEC. Graphical method type of blending overcomes the drawback of Optimal Blend Ratio (OBR) which gives an approximate solution. The composite blended gives good electrical, mechanical characteristics with good weathering resistance.
