Friction tape

Friction tape is a type of woven cloth adhesive tape, historically made of cotton, impregnated with a rubber-based adhesive. Sticky on both sides, it is mainly used by electricians to insulate splices in electric wires and cables. The rubber-based adhesive provides a degree of protection from liquids and corrosion, while the cloth mesh protects against punctures and abrasion. It has been supplanted by PVC-based electrical tape except commonly used for over wrapping.
