Advantages of liquid electrical tape over conventional electrical tape for covering exposed conductors is given below.
Explanation:
- Electrical tape and "regular" adhesive tape is that electrical tape is stretchy. This allows the tape to wrap around a wire junction and still grab the insulation to either side. This helps keep the tape in place.Where as Regular tape is likely to get stiff, lose adhesion, and slide away from the joint, leaving it exposed.
- The electrical tape is able to withstand much more heat and like the others said the adhesive is better and it can stretch 200 percent.
- Electrical tape is a suitable long-term or permanent solution in various applications.Heat-shrink sleeving, spiral wrap, flexible conduit, self-amalgamating tape, rubber sleeves, junction boxes, table ties/clips, grommets, cable markers, etc. are all better solutions for almost any given use of electrical tape other than to conventional electrical tape which has temporarily hold, bundle, insulate, or mark a cable.
- This kind of type is often used by electricians. It's typically made of slightly stretchy PVC vinyl, and is backed with a pressure sensitive rubber-type adhesive. It has good insulative properties, and is perfect for protecting wire splices and providing extra insulation on electrical cords. it's also available in a variety of other colors (like red, green, yellow, green, and white) that can be used for color-coding.
