This high-temperature tape is made from Kapton®† film and a cross-linked silicon adhesive. The tape is flame-resistant 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.
