This high-temperature tape is made from Dupont's trademark Kapton film and a cross-linked silicon adhesive. The tape is flame-resistant, will withstand short-term intermittent temperatures to 600 °F, and can be used as electrical and thermal insulation . Compared to electrical tape, it removes cleanly without leaving a residue, making it ideal for packing, temporarily securing components, or powder coating applications.

Kapton tape is commonly used as a wire and cable wrap as well as to protect electrical components during soldering. It is effective for both hand-soldering and mass soldering applications, such as wave soldering. In the electronics industry, Kapton tape is applied to circuit boards before wave soldering to shield gold fingers from the solder material and prevent unwanted electrical connections. The tape is also easy to trim with a razor blade and can be used as a temporary dust cover for ports in devices.
