PVC electrical tape PVC electrical tape is most widely used now, it with polyvinyl chloride ( ) Film as the backing material, made of pressure-sensitive adhesive evenly coated on the film, has good resistant to high voltage under 600 v, flame retardant, weather resistance and other properties. The color of PVC electrical tape is not monotonous, there are red, blue, green, white, black, yellow and so on multi-color optional. High-pressure rubber adhesive tape and a high pressure rubber adhesive belt, it is made up of rubber, oil, calcium powder delay pressure, maximum resistance to the high temperature of 150 degrees, ductility than electrical insulation tape is better, but the intensity of electrical insulating tape, the need for cooperation and PVC electrical tape.
