DuraStick® Polyimide (Kapton®) Tapes provide the greatest dielectric strength of any product in AFC’s line of tapes. These tapes are manufactured by applying a high-temperature silicone or acrylic adhesive to a polyimide film. Because of their unique properties, DuraStick® Polyimide Tapes are ideal for use as electrical insulation in the aerospace and electronics industries.

What are DuraStick® Polyimide (Kapton®) Tapes?

DuraStick® Polyimide Tapes are engineered to retain the distinctive properties of PTFE. By adding an adhesive to one side, the need for mechanical fastening is eliminated. DuraStick® Polyimide Tapes possess a thin, strong film which has excellent dielectric strength, chemical and moisture resistance, excellent tensile strength and modulus and weathering capabilities. These tapes, because of their coating of Kapton® film; offer a combination of properties, which make it ideal for electrical uses. These properties are maintained over a wide temperature range and used in field applications where the environmental temperatures as low as -269°.
