Test method for the tip of electrical tape:

Place the tape sample on a 3mm diameter metal bar in a semi-joint and place it at room temperature for a week before checking the tape. For example, in the heat treatment of general electrical components, it must be treated in the impregnated paint for more than 20 minutes. And heat treatment at 150 °C before immersion 30-60 minutes, and then check the adhesive tape warping, allowing an error of less than 3mm, 0-1 .5 mm is the best.
