Electrical and Mechanical Properties of acrylonitrile butadiene rubber / styrene butadiene rubber blends filled with carbon black

The electrical and mechanical properties of Acrylonitrile Butadiene rubber (NBR), styrene Butadiene rubber (SBR) and also on (NBR/SBR) blends with different compositions were studied before the addition of carbon black. The compatibility study which was carried out using different tools and techniques (Heat of mixing, dielectric and scanning electron microscope) indicate that such blends are incompatible. The electrical as well as the mechanical properties were carried out on of NBR and SBR to be loaded with different concentrations of high abrasion furnace black (HAF) in order to find out the percolation thresholds in relation to the net work formation.
