Investigations of the Influence of Compatibilizer and TiO2 Filler on the Properties of Thermoplastic Polyurethane/Polyolefins Blends
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 3
Abstract
Melt blending of thermoplastic polyurethane (TPU) with polyolefins (PO) can lower the cost and improve mechanical and chemical properties. Since thermoplastic polyurethane and polyolefins 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 TiO2 filler to enhance the mechanical properties were studied. Blends were produced by melt mixing using a single screw extruder. Mechanical and morphological properties were studies. The results show that the blend of thermoplastic polyurethane (TPU)/PO’s with suitable compatibiliser and mica gives excellent performance in all aspects.
