Terminate the tapes are made from soft polyvinyl chloride (
Film as the backing material, coated rubber pressure-sensitive adhesive. they, good insulation, flame retardant, resistance to voltage, cold-resistant features, it is suitable for automobile wiring, wire winding, insulation protection discontinue use tape and placed in the process of adhesive tape on the side stick dust and dirt, additional resistance and suction light phenomenon, further cause local underexposed.
in the practical work, especially the poor environmental conditions, often see tape edge with darker edge obviously, with such a tape collage's original version must be appear plate burning sun to tape mark because tape center theory belongs to the homogeneous medium, and the tape edge parts especially tape edge critical parts are not homogeneous medium, can produce different degree of light scattering, refraction and diffraction phenomenon.
In puzzle tape at the same time a circle around the edge of the how many will still exist air layer, the air layer produced optical path difference, caused the optical interference phenomenon.
These can cause tape edge part exposed more insufficient.
