Thermoplastic polyurethanes (TPUs) series were synthesized by mixing poly tetramethylene glycol (PTMG), polyethylene glycol(PEG) and Polypropylene glycol (PPG) as polyol, methylene diphenyl diisocyanate(MDI), hexamethylene diisocyanate(HDI) and isophorone diisocyanate(IPDI) as Isocyanate and 1,4-butandiol(1,4-BD) as chain extender based on different NCO index. Synthesized TPU materials were evaluated using universal test machine(UTM), viscometer and fourier transform infrared spectrometer(FT-IR). Mechanical properties were evaluated using Universal Testing Machine (UTM) and viscometer. Synthesized TPU materials exhibited high mechanical properties and light weight and high functionality for instrument panel applications.
