Thermoplastic polyurethane provides opportunities to the modern industry by its outstanding versatility, by improving the performance of any product from shoe sole, seals, films, conveyor belts and cables. Thermoplastic polyurethanes have high elongation and tensile strength, its elasticity and its ability to resist oils, greases, solvents, chemicals and abrasion. Thermoplastic Polyurethane are classified in to Polyether based and Polyester based, which have following characteristics within them, Polyester TPUs are unaffected by oils and chemicals, provide excellent abrasion resistance, offer a good balance of physical properties and are perfect for use in polyblends, but on the other side Polyether TPUs are slightly lower in specific gravity than polyester TPU’s and offer low temperature flexibility, good abrasion and tear resilience. They are also durable against microbial attack and provide excellent hydrolysis resistance – making them suitable for applications where water is a consideration. The mentioned work deals with preparation of nano composites based on thermoplastic polyurethane and nanosilica via melt blending process in a laboratory mixer and prepared nanocomposites were tested for mechanical/thermal/electrical/structural properties and also the irradiation properties were determined. The aim of this work is to obtain nanocomposites and the improved properties that those materials can display.
