聚醚酰亚胺在高温和应力下的长期抗蠕变性允许其在许多结构设备中代替金属和其它材料。在可变温度、湿气和频率条件下表现出很好的电性能。在GHz频率下的低损耗因数使聚醚酰亚胺具有高的微波可穿性。它的离子型污染物低水准，在 250F R． H．和207kPa下120小时用水提取后的导电率，在20兆欧以上，它可用作电子传感器元件的绝缘材料。

聚醚酰亚胺是优良的涂层和成膜材料，能形成适用于电子工业的涂层和薄膜，并可用于制造孔径 0.1μm、具有高渗透性的微孔隔膜。还可用作耐高温胶粘剂和高强度纤维等。

PEI板属于非结晶性塑料。是一种无定形的高性能聚合物，是用无定形PEI（聚醚酰亚胺）所制造的工程塑料经过挤出机高温挤出而成

PEI主要特性

1、PEI中文名字（聚醚酰亚胺）是琥珀色透明固体,有良好的阻燃性和低烟度,燃烧等级为UL94-V-0级。

2、PEI具有很强的高温稳定性.耐高温,热变形温度达220℃,可在-160一180℃的工作温度下长期使用。

3、水解稳定性很好,耐高温,耐蒸汽；

4、聚醚酰亚胺具有很好的抗紫外线、Y射线性能。

PEI应用

取代金属制造光纤连接器,可使元件结构 化,简化其制造和装配步骤,保持更 的尺寸。用于汽车领域,如用以制造高温连接件、产, 高功率车灯和指示灯、控制汽车舱室外部温度的传感器和控制空气和燃料混合物的传感器。还可用作耐高温润滑侵蚀的真空泵叶轮、在180℃操作的蒸馏器的磨口玻璃接头（承接口）、非照明的防雾灯的反射镜。
