Polyimide films shows excellent electrical insulation properties, high temperature resistant, and excellent solvent resistant. Polyimides are known for thermal stability, good chemical resistance, excellent mechanical properties, and characteristic orange/yellow color. Polyimides compounded with graphite or fiber reinforcements have flexural strengths. Polyimides exhibit very low creep and high tensile strength. These properties are maintained during continuous use to temperatures of up to 232 °C (450 °F) and for short excursions, as high as 400 °C (752 °F). Molded polyimide parts and laminates have very good heat resistance. Polyimides are also inherently resistant to flame combustion and do not usually need to be mixed with flame retardants. Polyimide tape’s primary uses are in electrical applications such as coil insulation, capacitor and transformer wrapping or insulation, magnetic wire insulation, and in gold leaf masking during wave soldering. It is also used as a very high temperature mask during powder coating applications.
