LOW HAZE THERMOPLASTIC POLYURETHANE USING MIXTURE OF CHAIN EXTENDERS INCLUDING 1,3-AND 1,4-CYCLOHEXANEDIMETHANOL

摘要

The present invention is a low haze thermoplastic polyurethane (TPU) prepared from a chain extender mixture that includes an acyclic diol and a mixture of 1,3- and 1,4-cyclohexanedimethanol. The TPU elastomers exhibit good optical clarity, particularly when formed into relatively thick injection molded parts.
