Working principle of PVC electrical insulating tape

 

The adhesive effect of the tape is caused by the moisture content of the adhesive on the surface of the tape. When the adhesive penetrates the tape, the tape dries quickly and becomes a part of the adhesive. Therefore, the micropore rate on the surface of the tape is very high. Select the tape if it has more porosity or greater hygroscopicity. Fast curing tapes must be used, and vice versa, i.e. slow curing tapes or tapes containing more adhesives. The tape is applied to the baseband. Generally, the tape must be completely dry before rolling. If the tape is too wet, the tape itself will stick very tight. It is difficult to open in use, and some cannot be used at all.
