Claim:
1. A thermoplastic polyurethane composition, comprising from 70 to 99.9% by weight, based on the total weight of the thermoplastic polyurethane composition, of a polyether-based thermoplastic polyurethane; and from 0.1 to 4.0% by weight, based on the total weight of the thermoplastic polyurethane composition, of a 1,2-cyclohexane dicarboxylic acid ester represented by formula (I): wherein R wherein the polyether-based thermoplastic polyurethane comprises: wherein the organic diisocyanate is at least one selected from the group consisting of diphenylmethane 2,2′-diisocyanate, diphenylmethane 2,4′-diisocyanate, diphenylmethane 4,4′-diisocyanate, dicyclohexylmethane 4,4′-diisocyanate, 2,4′-diisocyanate, and 2,2′-diisocyanate, wherein the polyol reactive toward isocyanate is a polytetrahydrofuran comprising a hydroxyl group and having a number average molecular weight of from 600g/mol to 2000g/mol, and wherein the chain extender is at least the one member selected from the group consisting of 1,2-ethylenediol, 1,4-butanediol, and 1,6-hexanediol.
