Elastomeric composites are widely used because of their light weight, design flexibility, and processability. However, these composites exhibit less attractive mechanical properties such as low strength and low elastic modulus when compared with metals and ceramics. Adding micron or nanosized inorganic filler particles to reinforce the polymeric materials has been standard practice in the composite industry for decades. The mechanical and physical properties of the composite are mostly dominated by the nature of the filler, whereas the polymer matrix determines the environmental characteristics of the composite. Therefore, the overall composite properties can be tailored to fit the desired application through proper choice of filler and matrix resin. Therefore, a judicious choice of type of the filler and its concentration in the composite will augment to overall performance of the composite. The ethylene vinyl acetate (EVA) / acrylonitrile butadiene rubber (NBR) compounds were mixed in a laboratory size (225 X 100 mm) mixing mill at a friction ratio of 1 : 1.25 according to ASTM D 3182 standards while carefully controlling the temperature, nip gap, mixing time, and uniform cutting operation. The temperature range for mixing was maintained at 80 r C by carefully circulating water
