| abstract |
The invention relates to a thermoplastic polyurethane material that has high flex modulus, low density, and is capable of withstanding repeated cyclic deformation. The thermoplastic polyurethane composition is formed from the reaction product of a polyol component, which includes a blend of a polyether polyol, such as poly(tetramethylene ether glycol), and polybutadiene diol, a diisocyanate component, and a chain extender component. |
