聚醚酰亚胺(PEI)的薄膜是无定形的,适用于高温应用。此外,它们还具有良好的热、机械和电气性能组合,以及极低的可燃性和燃烧过程中的烟雾释放水平。这些特性使PEI特别适合于电气和电子绝缘体。此外,在各种需要高温下高强度和刚度的结构部件中的应用都使用了PEI薄膜。聚醚酰亚胺能抵抗各种化学物质,并具有良好的抗紫外线和γ辐射能力。其玻璃化转变温度允许在高温下使用,同时保持高机械性能。在不同温度、湿度和频率条件下,电性能表现出很好的稳定性。而且,即使在很低的频率下,PEI薄膜也具有较低的耗散系数。 Films of Polyetherimide (PEI) are amorphous and suitable for high termperature applications. Additionally, they have an excellent combination of thermal, mechanical and electrical properties, along with very low flammability and low levels of smoke evolution during combustion. These features make PEI especially well suited for electrical and electronic insulators. Additionally, applications in a variety of structural components requiring high strength and rigidity at elevated temperatures have used PEI films. Polyetherimide resists a wide range of chemicals and has good resistance to UV and gamma radiation. Its glass transition temperature allows for use at high temperatures while maintaining the high mechanical properties. Electrical properties show very good stability under variable temperatures, humidity and frequency conditions. Moreover, PEI films exhibit a low dissipation factor even at very low frequencies. The color of this material is an orange amber. |
