Abstract: The instant disclosure related to a thermoplastic polyurethane composition (TPU) comprising the reaction product of an aromatic polyisocyanate and a diol mixture of a first and second diol where the second diol is at least 15 wt % of the diol mixture. The TPU reaction product further has a hard block content of at least 30 wt % based on the total weight of the TPU reaction product. The TPU compositions disclosed herein have high temperature stability and may be used in applications where high temperature stability is required, such as coating wires and cables or in seals and gaskets.
