Not all electrical tapes are the same, choosing the right tape for your application is essential for the quality of the electrical supply and the safety of the site. Here we explain the common types of electrical tapes and their purposes.
The most common types are the Vinyl tape, the Mastic tapes, and the Rubber tapes; using a combination of these tapes will help to achieve the desired result.

Vinyl backed tapes have a strong, flexible, abrasion resistant PVC backing which provides a barrier from moisture and corrosive elements. They are often the first and most economical choice for primary and secondary insulation.
Mastic tapes offer excellent adhesion and sealing characteristics to metals, rubbers, synthetic cable insulations, and jackets. They provide UV resistance and are designed for outdoor conditions because they quickly and easily resist moisture.
Rubber tapes are designed for use in splicing and terminating wires and cables with options rated up to 69kV. They have excellent physical and electrical properties and are ideal for adding moisture protection and padding to electrical connections and cables.

Vinyl electrical tape is versatile. Its main job is to insulate but a good tape will form a tight seal that resists corrosive contaminants.
Protect and insulate your electrical installation with Vinyl Electrical Tapes. Most have a strong, flexible PVC backing and excellent insulating properties, they withstand moisture, abrasion, corrosion, alkalis, and acids. Hot or cold weather? Options are available for the vinyl electrical tapes that are flame retardant, UL Listed and CSA certified in a wide range of operating temperatures.
When you are working with odd shaped components or needing to tuck in some insulation where your tape won’t reach; mastic is the product to use. Think of it as putty on a roll.
Pad, protect and insulate electrical connections up to 600 volts with. Need to apply an insulating barrier or moisture-seal to an odd shape? Mastic Tapes are made of a self-fusing, butyl rubber-based insulating compound. Mastics tapes are available with a vinyl (PVC) backing, a primary insulating rubber backing, or no backing at all.
Primary Insulation helps keep the lights on.
Electricians have critical jobs. Keeping our world powered requires concentration, knowledge, and skill. Some of the most dangerous work is done by electricians working on medium and high voltage applications. Ethylene propylene and silicone rubber electrical tapes have the highest dielectric rating of electrical tapes made by 3M and are a trusted product in the toolbox of most medium and high voltage linemen and installers. With proper wrapping, their self-fusing properties help to eliminate voids in critical areas that may cause catastrophic failures.
But there is more. Pros know that rubber tapes can offer more than just high voltage insulation and are often used in a variety of low voltage applications as well.
