聚酰亚胺制品是琥珀色半透明或不透明，或是深褐色的固体。有突出的耐高温（使用温度250°C），耐幅射性，良好的机械强度，可制成薄膜，增强塑料、模压品、耐高温、高真空的润滑轴承，高温下使用的电气设备零件及耐幅射的制品等，也可作介电材料如插头、插座各种电器设备的骨架线架等。在聚酰亚胺中加入适量的四氟和石墨可作为高速压缩机中用的无油润滑材料，如活塞环密封圈、轴瓦等
Polyimide article is a solid mass with the colour of translucent or opaque amber, or deep brown. It has good mechanical intensity and possesses the superior properties against high temperature (working temperature 250°C) and radiatin. Polyimide article can be made into thin film, strengthened plastic moulding article, high-vacuum selflubricating bearing of resistance to high temperature, parts of electric apparatus used in high temperature, articles of resistance to radiation and so on. It can also be used as dielectric materials, such as plug, socket, skeleton and wire rack of different electrical applicance, etc.Polyimide added in with a moderate amount of polytetrafluoroethylene(PTFE) and graphite can be used as oilless lubricating material used in high-speed compressor, such as piston ring sealing ring, axle rim, etc.
