Vinyl tape forms the final outer layer and serves several important functions in addition to electrical insulation, including abrasion protection, corrosion resistance, UV resistance, and protection from chemicals including alkalis and acids. Conformable vinyl tape is tougher than the softer, stickier surfaces of rubber, mastic, and putty tapes it protects.
Self-adhesive electrical tape also comes in a variety of colors, making it easy to color code your electrical wiring. This can help you quickly identify different circuits or connections, saving time and reducing the risk of errors.
