Problem statement Polymer nanocomposite material in general and rubber nanocomposite in particular are particularly interested in research and development in the time to come because they have many superior properties superiority. In rubber applications reinforcement mostly used in orrder to create better quality products and reduce costs active fillers . Traditional reinforcement in the rubber industry such as black coal silica clay powder. These enforcements were predominantly micro-sized at lower costs so they are often referred to as fillers active or inert fillers . Rubbers are reinforced with these materials are called composite rubbers. Different from rubber composite rubber nanocomposite was reinforced with nanometer-sized fillers their size has one of three dimensions below 100nm nanocomposite rubbers were created by different techniques such as mixing in a melted state mixing in solution mixing in latex state followed by method of coagulation and polymerisation around filler particles. Compared to rubber reinforced with micro fillers rubbber reinforced with nano fillers has better stiffness modular .
