The first commercially available version of the tape was sold for use as a wire-harness wrapping. This original electrical tape wasn't black. Tapes formulated for high-temperature were yellow, and later versions were white. Electrically insulating tapes are essential for enhancing functionality and reliability in a wide range of applications. Some of the most popular types include electrically insulating adhesive tape and electrically insulating film, both of which provide reliable electronic isolation and ensure that a direct electrical connection is not made between two or more circuits or their adjacent parts. There is also electrically conducting tape for shielding and similar applications. White tape, because of its instability in ultraviolet light, was eventually replaced with black tape, although colored vinyl tapes are still used as identification and marking tapes. Black became the standard industry color for vinyl standard tape, primarily because of its ultraviolet resistance. Thicknesses originally were 4 mil (100 μm), 8 mil (200 μm) and 12 mil (300 μm). These were standardized to 7 mil (180 μm) and 10 mil (250 μm) in 1948.

Experiments were conducted by combining new plasticizers with the white, flour-like vinyl resin. Finally, in
January 1946, inventors Snell, Oace, and Eastwold of 3M applied for a patent for a vinyl electrical tape with a plasticizer system and non-sulfur-based rubber adhesive that were compatible.

of the wire (colored tape sometimes is called "phasing tape"). When wires are phased, a ring of tape is placed on each end near the termination so that the purpose of the wire is obvious. The following table(s) describe the use of electrical tape.

A wide variety of electrical tapes are available, some for highly specialized purposes. "The primary tapes used in electrical applications are vinyl, rubber, mastic, and varnished cambric."
