ABSTRACT
Polyimides are used extensively in situations requiring high-performance plastic materials, where other engineering materials do not function, because of their unique combination of superior mechanical, electrical, chemical and thermal properties. Kapton, a popular polyimide, is able to operate in temperature extremes as low as –269°C and as high as 400°C [1]. In particular, its excellent insulating properties, together with radiation resistance, and fire resistance, have made this polyimide one of the favorite choices for applications in wire and cable insulation, electrical component seal assemblies, and component leads in nuclear power plants, military aircraft, and space shuttles [2,3]. Other applications include various electronic components such as flexible circuits, semiconductor pads, microprocessor chip carriers, coil insulation, magnetic wire insulation, and solar arrays.
