A variety of polymeric materials (polyurethane, polypropylene, polyethylene and polyvinylidine copolymer) have been evaluated for suitability in making of air-filled balloon to detect intraluminal pressure. The polyurethanes, in particular ECD, proved to be most suitable because of the ease of fabrication, low permeability to air and high frequency characteristics. Polyvinylidine copolymer was adequate but suffered from difficulties in fabrication. Polypropylene and polyethylene, available in film, were troublesome in making balloon and displayed low frequency characteristics.
人们对多种聚合材料（聚氨酯、聚丙烯、聚乙烯和聚偏二烯共聚物）进行了评估，以确定其在制造用于检测腔内压力的充气气球方面的适用性。事实证明，聚氨酯，尤其是ECD，是最合适的，因为其易于制造、空气渗透率低且具有高频特性。聚偏二烯共聚物是足够的，但在制造方面存在困难。以薄膜形式提供的聚丙烯和聚乙烯在制造气球时很麻烦，并且显示出低频特性。
