Abstract

This invention is directed to a thermoplastic polyurethanes composition comprising polyether-based thermoplastic polyurethane and 1,2-cyclohexane dicarboxylic acid ester and preparation processes thereof. The thermoplastic polyurethane composition has a good mold release behavior in injection molding without undesirably significant shrinkage and surface blooming of final product.
