A polyimide film electrical tape works to great effect in any high or low-temperature applications especially in PCB applications. It is commonly used to mask areas such as the gold fingers on a circuit board for protection during wave soldering.

RS PRO polyimide electrical tape is available in different sizes; width: 12 mm x length: 33 m, width: 19 mm x length:33 m and width: 25 mm x length: 33 m.

Polyimide is made from a synthetic resin where various polymer units are linked via Imide groups. Polyimide stems from the word Polymer. A polymer is a substance of very large molecules/macromolecules, made of units submerged together.

Polyimide tape is a high-temperature film tape often used in electronic circuit board production, insulation during wave soldering, and electronic applications.

There is a range of speciality masking tapes suitable for more specific applications. These tapes usually boast qualities that enable them to work in more extreme environments. Heat resistant foil masking tapes can be suitable for use in hot zones as well as being used in conjunction with a flame. Higher-strength tape is used for stronger, thicker backing material that can be subjected to abrasives such as sandblasting.
