There are ELECTRICAL PVC TAPES offered by us that are electrical insulation tapes, which are usually referred to as electrical insulation tapes or insulation tapes in the industry. They are made of PVC film as the base material and coated with rubber pressure sensitive adhesive. Electrical tapes are made to be an insulating material itself but covering the tape with another layer of insulation is generally not a safe idea. Pressing a flammable insulation against electrical tape can put you at a potential for hazard, so make sure to choose between one or the other. ELECTRICAL PVC TAPES are made for use in the various places.
