Electrical tapes are typically made with a polyvinylchloride (PVC) backing and a non-corrosive rubber-based adhesive. The backing is what gives it the ability to stretch and conform to cables and wiring. This stretch is a critical characteristic of electrical tapes because it allows the tape to wrap tightly around cables for long-lasting insulation. Most cloth, film, and other types of tapes do not possess the elongation characteristics that allow electrical tapes to function properly.
PVC tape is one variety of electrical tape, as mentioned above. Functional and durable, PVC (polyvinyl chloride) tape is considered a ‘balanced’ plastic tape and is used in similar situations to vinyl electrical tape. However, PVC tape copes well with environmental factors and is often used for outdoor applications.
