Abstract: A transparent polyurethane has exceptionally high heat distortion temperatures, that is at least 280.degree. F. at 264 psi, as well as good light transmission, ultraviolet light resistance, abrasion resistance, and the like. The urethane intermediate is one or more very low equivalent weight, multifunctional hydroxy containing compounds so that when reacted with a polyisocyanate and cured with a low equivalent weight, multifunctional polyol, a highly crosslinked polyurethane is produced.

Abstract: An extrudable urea-extended thermoplastic polyurethane elastomer is formed from at least one aliphatic diisocyanate, at least one polyester glycol or polyether glycol, and at least one diamine curing agent. At least one second diamine curing agent and/or at least one extrusion processing aid may be included. The polyurethane has high-temperature-resistance and is thus extrudable at high temperatures. The polyurethane is also strong and durable. The polyurethane can be liquid-cast, transfer-molded, sprayed, and extruded without changing either the chemistry or stoichiometry of the polyurethane. The polyurethane may be used for making vehicle air bags or other any application for thermoplastic urethanes which requires increased thermal stability.
Abstract translation: 可挤出的尿素延伸的热塑性聚氨酯弹性体由至少一种脂族二异氰酸酯，至少一种聚酯二醇或聚醚二醇和至少一种二胺固化剂形成。 可以包括至少一种第二种二胺固化剂和/或至少一种挤出加工助剂。 聚氨酯具有耐高温性，因此可在高温下挤出。 聚氨酯也坚固耐用。 聚氨酯可以液态铸塑，转移模塑，喷涂和挤出，而不改变聚氨酯的化学成分或化学计量。 聚氨酯可用于制造车辆气囊或其它任何需要增加热稳定性的热塑性聚氨酯的应用。
