Electrical tape (or insulating 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 vinyl is most popular, as it stretches well and gives an effective and long lasting insulation. Electrical tape for class H insulation is made of fiberglass cloth. Vinyl or PVC electrical tape is usually supplied on a roll or spool. White, black, pink, red, and blue electrical tape colors are commonly used for wire marking. Both wide and thin electrical tape is available in a range of widths and thicknesses.  Electrical tape tape is useful for color coding or “phasing” wires, motors, or preparing a wire head before a pull. The super durable vinyl resists typical wear and tear, and the flexible backing has rubber-based adhesive that bonds even to irregular surfaces. Electrical tape works best when it conforms to the object it is being applied to. So, when you apply electrical tape to a cord, piece of wire, or anything else, stretch the tape as you wrap. The tape will adhere better and will provide more insulation protection than when it is applied loosely. A type of thick adhesive tape used chiefly to cover exposed electric wires.  Electrical Tape is a colored PVC Electrical Insulation Tapes with Rubber based adhesive, which is flame retardant and cold weather resistant. Used generally for insulating, protection, and color-coding of electrical wires; and for wire harnessing in the automotive industry.
