Abstract: An inflatable member such as a balloon which is formed at least in part of a polyamide/polyether block copolymer thermoplastic elastomer, commonly referred to as polyether block amide (PEBA). The presently preferred PEBA copolymer is polyamide/polyether polyester copolymer, such as PEBAXnull. The balloon of the invention exhibits high tensile strength, high elongation, and low flexural moduli. The balloon may be formed as a single layer of PEBA, or as a multilayer coextrudate having at least one PEBA layer. The balloon may be 100% PEBA or a blend of PEBA with another polymer, such as nylon.

Abstract translation: 至少部分由聚酰胺/聚醚嵌段共聚物热塑性弹性体形成的可膨胀构件，例如气球，通常称为聚醚嵌段酰胺（PEBA）。 目前优选的PEBA共聚物是聚酰胺/聚醚聚酯共聚物，例如PEBAX。 本发明的气囊显示出高拉伸强度，高伸长率和低弯曲模量。 气囊可以形成为单层PEBA，或者形成为具有至少一个PEBA层的多层共挤出物。 球囊可以是100％PEBA或PEBA与另一种聚合物如尼龙的混合物。
