The full name of electrical tape is polyvinyl chloride electrical insulation adhesive tape, also known as electrical insulation tape or insulation tape. Electrical tape is suitable for insulation of various resistance parts. There are generally three types of electrical insulation tape: one is insulation black tape, the second is PVC electrical flame-retardant tape, and the third is high-voltage self-adhesive tape. Each of the three has its own function. How to determine the quality of electrical insulation tape when selecting it?


Electrical insulation tape is divided into three types:
One type is insulation black tape, which only has insulation function but is not flame retardant or waterproof. Now it has gradually been screened, and it is still used in some civil building electrical systems.


The second type is PVC electrical flame-retardant tape, which has three functions: insulation, flame-retardant, and waterproof. However, because it is a PVC raw material, its ductility is poor, and it cannot tightly wrap the joints. Its waterproof performance is not ideal, but it is now widely used.


The third type is high-voltage self-adhesive tape, which is generally used on higher voltage levels because of its good ductility and superior waterproofing compared to the second type. Therefore, it is also applied in the low-voltage category. However, because its strength is not as strong as PVC electrical flame-retardant tape, these two types are generally used in combination.

Quality differentiation of electrical tape
From an external perspective, it can be seen whether there are defects, whether the tape rewinding is comfortable, whether there are burrs on the slitting, and whether it is smooth. Check the raw materials of the tape (there are many varieties of electrical insulation tape, so we won't introduce the quality of the materials one by one. In most cases, it still depends on the application situation). When looking at the glue, most of the glue has now evolved towards environmental protection, and the taste is very important. If it is very pungent, it is more likely to be defective (not all tapes), Is there any reverse adhesion when using the tape when pulling it down, and is there any residue when tearing it off after use? If the residue is on the product, this is the fatal point of defective tape. PVC information is basically similar, mainly looking at the adhesive. Poor quality tape can be wrapped for a period of time, and then untied to see the separation of the adhesive and PVC information, which looks sticky and uncomfortable, while high-quality tape will not show this problem.
