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.


Self-fusing silicone electrical tape finds applications across various industries. In electrical installations, it is commonly used for insulating splices, protecting wiring, and securing cables in both residential and commercial projects. Its resistance to heat makes it an ideal choice for high-performance applications, such as in automotive and aerospace sectors.
In simple terms, a rubber based pressure-sensitive consists of a natural or synthetic rubber to which various tackifying resins are added along with plasticizers, antioxidants, pigments, and UV stabilizers. These formulations can be delivered to the coating machine dissolved in organic solvents, dispersed in water, or in molten form as a hot melt. Some synthetic elastomers are also curable by radiation such as UV or electron beam(EB).
However, if you do intend to build your own well pump control box, make sure you’ve got well pump wiring diagrams on hand, as well as the technical specs of the pump you’re using. It’s common to install a well pump control device in an outdoor electrical box , and if that’s part of your plan, make sure to invest in an outdoor enclosure .
