Tworoll mill mixing technique, solution casting, internal mixer and melt mixing are the most widely used techniques [14, 15]. Among them, mixing of rubber with nanofillers in a tworoll mill provides a high shear rate which is the most suitable technique used in rubber industries to disperse the nanometric particles into the polymer matrix.
