Electrical tape is a type of pressure-sensitive tape used to insulate electrical wires and other material that conduct electricity. It can be made of many plastics, but vinyl is most popular; it stretches better, giving a more effective and longer lasting insulation.

Electricians generally use only black tape for insulation purposes. The other colors (and black) are used to indicate the voltage level and phase of the wire. (In fact, the colored tape is refered to as "phasing tape".) This is done on large wire which is available only in black insulation. (Colored wires are never phased.) 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 describes this usage. An electrician is a tradesman specializing in electrical wiring of buildings and related equipment. ...

The tape is usually available in hardware stores. The fact that it is often more UV-resistant than other tapes and its ability to stretch has led to a wide range of uses beyond insulation.

Alternative Usage

Electrical tape is often also used to secure lighting cables to the truss in stagecraft, and is commonly known as LX tape for this reason. Stagecraft (or Technical Theatre) is the art of building, attaching, and rigging scenery for theater and television as well as other technical aspects of performance including sound, costuming, makeup, and lighting. ...


Electrical tape is often used by front rowers in rugby to tape back their ears. This is to prevent abrasion from causing cuts or problems like cauliflower ear.

Marching percussionists use electrical tape to wrap their sticks. The purpose is twofold: the first being the increased durability and the second being increased visibility against marching uniforms, making stick movement and uniformity more obvious.


Before the introduction of mass produced roller hockey pucks, certain brands of electrical tape were used as a puck substitute given that traditional ice hockey pucks are poorly suited for use on concrete and asphalt. Scotch 88 tape, in particular, was commonly used even in organized leagues during the 1990s. Roller hockey is a category which includes two rollersports. ... Two standard hockey pucks. ...


The fact that electrical tape is stretchy, easily torn by hand, can be written on, and generally removes from smooth surfaces cleanly makes it useful for a number of other applications, including color coding, labelling and temporarily taping objects together.


Electrical tape is torn by grasping it between the pointer fingers and thumbs of both hands with thumbs touching. Pulling the hands apart stretches the tape until it breaks (about 4 inches.) When used to temporarily hold together a bundle of wires (or other objects), a tail is preferred for easy removal. After wrapping the bundle, twisting the roll several times so the tape wraps around itself then pulling away from the bundle creates the tail.


As a quick fix, electrical tape can be used as quite an efficient temporary bandage. This can be said about any other tapes as well. Bandages are also used for martial arts. ...


Additional Information

In the early 1940s, vinyl plastic emerged as a highly versatile material for a wide range of applications, from shower curtains to cable insulation. Making it work for tape, however, was a different story.


A major ingredient in vinyl film was tricresyl phosphate (TCP), which was used as a plasticizer. Unfortunately, TCP tended to migrate, giving the surface of the vinyl film an oily quality and degrading every tape adhesive known. Research chemists and engineers at 3M™ set out to create a dependable, pressure-sensitive tape made of vinyl film that would have the required electrical, physical and chemical properties.


Experiments were conducted combining new plasticizers with the white, flour-like vinyl resin. Finally, in January 1946, inventors Snell, Oace, and Eastwood of 3M™ applied for a patent for a vinyl electrical tape with a plasticizer system and non-sulfur-based rubber adhesive that were compatible. The first commercially available version of the tape was sold for use as a wire-harness wrapping. Interestingly, this original black tape wasn't black at all. Tapes formulated for high-temperature were yellow, and later versions were white. 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, 8-mil and 12-mil caliper. These were standardized to 7-mil and 10-mil in 1948.
