Mica tape and insulation Kraft paper tape are both used for cable insulation, but they have different properties and uses.
Mica tape is made by coating a layer of phlogopite or synthetic mica with a high-temperature resistant adhesive and then winding it onto a carrier. It has excellent electrical insulation and high-temperature resistance properties, making it suitable for use in cables that are exposed to high temperatures, such as power cables and heating cables.
Kraft paper tape, on the other hand, is made from kraft paper that has been impregnated with a resin or latex binder to improve its mechanical strength and water resistance. It is often used as a wrapping or filling material for cables to provide mechanical protection and moisture resistance.
In some cases, mica tape and Kraft paper tape may be used together in cable insulation. For example, mica tape may be used as the primary insulation layer, with Kraft paper tape used as a secondary insulation layer for additional mechanical and moisture protection.
