Electrical tape is a type of adhesive designed to work with electrical conduits. It is specially made with materials that do not conduct electricity.

Electrical tape  is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics but PVC  is the most popular,

as it stretches well and gives effective and long-lasting insulation. Electrical tape for class H insulation is made of fiberglass cloth.

Applications of Electrical Tape

Electrical tape is used to insulate electrical wire and secure lighting cables. Today, because of its usefulness, electrical tape is used not only by electricians, but also by homeowners, athletes, and musicians. Homeowners often use it for DIY projects around the house, athletes typically use it to mark indoor courts, and musicians often use it to do things like wrap their drumsticks for grip and comfort.

Materials Used in Manufacturing Electrical Tape

Sometimes electrical tapes are made from a type of plastic, but they are usually of a vinyl origin, as vinyl is stretchable, easy to tear, and long lasting.

Electrical Tape Design and Customization
Typically, electrical tapes are black in color, because black is resistant to ultraviolet light, but electrical tapes of other colors have their place as well. Namely, many electricians use different colored electrical tapes to help them differentiate between various phases of wires and voltage levels. This practice is so common that some colors of electrical tapes have come to indicate certain things almost universally. Green tape, for example, is used on earth ground wires, while brown tape has come to represent high voltage, phase A wires. Conversely, blue tape is understood to represent low voltage, phase C wires.

In addition to color variations, electrical tape can have different backing thicknesses, total thicknesses, dielectric strengths, tensile strengths, widths, backing materials, adhesive types, lengths, and levels of storage stability. Also, if an electrician or other user so chooses, he or she can wrap exposed wires in foil tape for additional protection. No matter their exact material composition, their color, their thicknesses, their width, or their strengths, all electrical tapes, as a rule, are UL-certified to not catch fire or burn if overheated. This provides a guarantee that the tape is safe to use with exposed wire.

How to Safely and Effectively Use Electrical Tape

To adhere electrical tape to exposed wires, users must carefully wrap the roll around the wire so the tape comes off the roll and goes onto the wire smoothly without sticking to itself. To keep the tape on the wire as they wrap it, users should also apply light tension. Also, the tape must be wrapped in such a way that there are no gaps where moisture can get in or the wire itself can be exposed to people.

Finally, the tape must be wrapped tightly, but not so tightly that it stretches too far, as over-stretching will cause it to change shape and loosen. Once applied, electrical tape can stay in place for many years without becoming weak, but it can still be removed easily without leaving adhesive on the wire.

Points to Consider When Purchasing Electrical Tape

Upon occasion, electrical tapes are alternatively referred to as friction tape or insulating tape. In addition, if they are made out of plastic, electrical tapes are sometimes known as PVC electrical insulation tape. It is important that electrical tape shoppers do not get PVC electrical tape confused with PTFE tape.

PTFE tapes are used to color code pipes in the same way that electrical tapes are used to color code wires. This similarity could give way to DIY-style homeowners purchasing PTFE tapes when they should be purchasing electrical tapes. Interested parties should note that electrical tapes, while they can serve similar purposes as PTFE tapes, are distinct from them.

In particular, PTFE tapes, which are often used to highlight areas on the floor, exhibit particularly high levels of abrasion resistance, and they can leave residue behind when they are removed. Mixing these two up could lead to problems down the line when a homeowner or electrician goes to strip the wires of this tape, such as adhesive residue on the wires.
