聚醚酰亚胺，polyetherimide简称pei，是琥珀色透明固体，不添加任何添加剂就有固有的阻燃性和低烟度，氧指数为47%，燃烧等级为ul94-v-0级，密度为1.28~1.42g/cm3。pei具有很强的高温稳定性，即使是非增强型的pei，仍具有很好的韧性和强度。因此利用pei优越的热稳定性可用来制作高温耐热器件。具有优良的机械性能、电绝缘性能、耐辐照性能、耐高低温及耐磨性能，并可透过微波。pei还有良好的阻燃性、抗化学反应以及电绝缘特性。玻璃化转化温度很高，达215℃。pei还具有很低的收缩率及良好的等方向机械特性。加入玻璃纤维、碳纤维或其他填料可达到增强改性的目的；也可和其它工程塑料组成耐热高分子合金，可在-160～180℃的工作温度下长期使用。
美国保险商实验室规定聚醚亚胺树脂的长期使用温度是338t和356t（根据等级），燃烧等级达到ul94v—0（10密耳厚度。）氧指数达47，聚醚酰亚胺符合飞机内件要求的faa阻燃性和热稀放性的材料标准。它的玻璃化转变温度为419f，并允许在392f下间断使用，在更高温度下，产生短期偏移。在356t下，拉伸温度和挠曲模量分别在41和2068mpa以上。用玻纤、碳纤维增强的材料在接近玻璃态转变温度下，具有更高的强度和刚度。
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 250f100% 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
