How to judge the quality of electrical insulation tape? How many electrical insulating tapes are there?
- Aug 06, 2018 -

Black PVC insulation tape

It has only insulation function, but it is not flame retardant or waterproof. It has been gradually eliminated, and it is only used in some civil buildings.

It has three functions of insulation, flame retardant, and waterproof. However, since it is made of pvc material, it has poor ductility and cannot be wrapped tightly. Water resistance is not ideal, but it is now widely used.

Generally used in higher voltages, because of its good ductility, it is worse than the second in waterproofing, so people apply it in the field of low voltage, but because its strength is not as good as pvc electrical flame retardant tape. Usually these two are used together.


The quality of the electrical tape is distinguished from whether it is smashed from the outside, whether the tape is re-rolled, whether there is any burrs, whether it is smooth or not. (There are many types of electrical insulation tape, so it is not good to judge the quality of the material. In most cases, you have to look at the use case). Look at the glue, now most of the glue has evolved into the environment, the taste is very important, if it is very pungent, it is more likely to be defective (not all tape), there is no anti-stick when the tape is pulled down, After use, there is no residual glue after tearing. If the residual glue is on the product, this is the deadly point of the defective tape.


Matters needing attention: PVC material is basically the same, mainly looking at the glue, after the tape of poor quality is wrapped for a period of time, and then untied, you can see the separation of glue and PVC material, it looks sticky, very uncomfortable, and good quality. This problem does not occur with the tape.
