Improvement of mechanical and chemical properties can be achieved by melt blending of thermoplastic polyurethane (TPU) with polyolefins (PO’s). Since TPU and PO’s are completely immiscible polymers, property enhancement cannot be attained. Effect of incorporation of polypropylene copolymer (PPCP), TPU-g-MA, TPU-g-AA as compatibiliser on the miscibility of the blends and effect of mica filler to enhance the mechanical properties were studied. A single screw extruder was used to manufacture blends by melt mixing. The results of mechanical and morphological properties show that the blend of thermoplastic polyurethane (TPU)/PO’s with suitable compatibiliser and mica gives excellent performance in all aspects.
