Abstract: A polyurethane elastomeric composition includes the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component includes a polydiene polyol present in the isocyanate-reactive component in an amount of greater than 0 and less than about 95 parts by weight based on 100 parts by weight of the isocyanate-reactive component. The polydiene polyol has an average hydroxy functionality of no greater than about 3 and a number average molecular weight of from about 1000 to less than about 2000 g/mol.
