What kinds of electrical tape are there? How to judge the quality of electrical insulating tape

The full name of electrical tape is PVC Electrical Insulation Tape, which is also called electrical insulating tape or insulating tape. PVC Electrical Insulation Tape is suitable for the insulation of various resistance parts. There are three kinds of PVC Electrical Insulation Tape in general. One is insulating black tape, the second is PVC electrical flame retardant tape, and the third is high-voltage self-adhesive tape. The three kinds have their own functions. When purchasing electrical insulating tape, how to judge the quality of PVC Electrical Insulation Tape? Insulating black tape

It only has insulation function, but it is neither flame retardant nor waterproof. Now it has been gradually eliminated. It is only used in the electrical of some civil buildings.

PVC electrical flame retardant tape

It has three functions of insulation, flame retardant and waterproof, but because it is made of PVC, it has poor ductility, can not wrap the joint tightly, and the waterproof is not very ideal, but it has been widely used now.

High pressure self-adhesive tape

It is better than PVC in the low-voltage application because of its higher ductility.

Quality discrimination of electrical tape

First, check whether there are defects from the outside, whether the tape rewinding is fit, whether the slitting has rough edges, and whether it is smooth. Check the tape material (there are many kinds of PVC Electrical Insulation Tape, so we won't introduce the quality of the material one by one. In most cases, it depends on the use).

Look at the glue. Now most of the glue has evolved to environmental protection, and the taste is very important. If it is pungent, it is more likely to be a defective product (not all tapes). Is there any anti adhesion when the tape is pulled down for use, and is there any residual glue when it is torn off after use? If the residual glue is on the product, this is the fatal point of the defective tape.

Note: PVC materials are basically the same. It mainly depends on the glue. If you untie the tape after wrapping it for a period of time, you can see that the glue and PVC materials are separated. It looks sticky and uncomfortable, but the tape with good quality will not have this problem.
