How to distinguish the quality of PVC electrical tape?

PVC electrical tape has the characteristics of waterproof, strong viscosity, high temperature resistance and excellent electrical insulation. PVC electrical tape is often used for the insulation of wire wrapping and wire ends, which involves the safety of electricity use. Therefore, it is an important choice for every power company and electrician to choose a roll of high-quality PVC electrical tape. How do we judge that the PVC electrical tape we buy is a high-quality tape?

First of all, we should start from the appearance of PVC electrical tape. A good electrical tape should have uniform color, flat cross section, and no protrusion or glue overflow. If the glue overflows, it proves that the glue of this roll of electrical tape has been aged. Wrap the film wire head with this aged tape, and the connection will loosen after a short time, causing electric leakage, which is a very dangerous consequence.

Secondly, we can pull off the electrical tape and feel the peeling force and adhesion of the tape surface with our hands. Generally speaking, the peeling force of the tape is moderate. If it is too light, it is difficult for us to wind the wires. If it is too heavy, it is difficult for workers to pull and easily deform the tape. The adhesive tape should be stronger, but the stickier the tape is, the better it is. As far as the characteristics of rubber are concerned, the rough surface of the tape proves that the glue is badly made, which is easy to break.

Finally, we stretch the tape to twice as long as we can to see the whitening of the tape. If the color of the tape does not change or only changes a little, it shows that there is no filler added to the base material of the tape, or only a little filler added. If the color of the tape becomes very white, it shows that the manufacturer has added a lot of filler to the PVC base material in order to reduce costs, The insulating property of the tape is reduced.

Therefore, a roll of electrical tape with flat cross section, moderate viscosity, and no or only a little white is a roll of good quality tape.
