Polyimide films are employed because of their extreme heat resistance. Service temperatures range from -100 °F to +500 °F (-73 °C to +260 °C). These flame retardant films exhibit high tensile strength and conformability, good solvent resistance, excellent dielectric strength and good abrasion resistance.

Polyimide tape applications include electrical insulation, capacitor, transformer, and coil wrapping, electronic assembly, and wave solder protection.
