Electrical tape, at the most basic level, is the choice of electricians for insulating wires and other materials the conduct electricity. Though some tapes are made of plastic, vinyl tape stretches better and yields a more durable protective insulation.
3M invented vinyl electrical tape, and continues to be the quality standard of the industry. Not all electrical tapes are the same, however. Please read below for a better understanding of the differing characteristics and applications of each type of tape.
3m 1710 Tartan electrical tape is considered to be general use tape. It is a black, 7 mil thick vinyl constructed tape. Inexpensive and relatively durable, Tartan 1710 insulating tape resists abrasion, moisture, alkalis, acid, copper corrosion and weather (including ultraviolet rays). Flame retardant and UL-listed, this is basic electrical tape that is often imitated, never equalled, and found in toolboxes the world over.
Scotch Vinyl 35 electrical color coding tape is 7 mil, premium tape. It is available in nine fade resistant colors. Color coding is often done for phase identifications, color coding leads and piping systems, and for marking safety areas. Abrasion and weather resistant, flame retardant.
3m Scotch Super 33 plus is a 7 mil premium vinyl electrical tape. Distinguishable by its super stretchy and conformable nature, regardless of environment. PVC backing provides electrical insulation for splices up to 600V. Resists UV rays, abrasion, moisture, copper corrosion, acids and alkalis, and works great in 0 to 220 degree F temps.
3m Electrical Moisture sealant is heavy duty, 45 mil, self-fusing, rubber-based thin insulating mastic compounds laminated to a flexible, all-weather PVC backing. The tape is designed for moisture sealing of electrical connections up to 600V.
