A thermoplastic polyurethane is the reaction product of a polybutadiene diol, a polyester diol, and a isocyanate component. The polybutadiene diol has a weight average molecular weight (M.sub.w) of from 200 to 20,000 g/mol. The polyester diol has a melting point of from 40 to 90 C. The reactants allow the thermoplastic polyurethane itself to have a melt flow index measured at 120 C. and 22.6 kg of from 0.1 to 200 grams, per 10 minutes as measured according to ASTM 1238. The thermoplastic polyurethane also has a melting point of from 50 to 300 C. The theiinoplastic polyurethane is used to form a composite article.
