For PVC electrical insulating tape, electrical tape full name again someone called electrical insulation tape or insulating tape. General electrical insulating tape has 3 kinds, one kind is black insulation tape, the second is electric flame retardant PVC tape, high pressure, for a third since the adhesive tape, three have different functions. The choose and buy the electrical insulating tape, how to judge the stand or fall of electrical insulating tape?

electrical tape classification < br />

the first is a black insulation tape, as long as the insulation function, but not flame retardant is not waterproof, now has been gradually screened, as long as there is in some civil construction electrical people in use.

the second is electric flame retardant PVC tape, it has the waterproof insulation, flame retardant, and three kinds of function, but because it is PVC material, so the poor ductility, cannot joint package is very strict, water proofing property is not very ambitious, but now it has been widely used.

  The third is a high pressure since the adhesive tape, general use on the level of high voltage, due to its good ductility, more astonishing than the second on the waterproof, so people also apply it in the category of low pressure, but because of its strength than PVC flame retardant tapes, generally using the two kinds of cooperation.

electrical tape quality distinguish

from outside is defective, tape whether rewinding and submissive, whether did cutting burrs, smooth the tape raw materials ( Electrical insulating tape, there are many varieties, and in most cases, depending on the application situation) Most is to see glue, glue now environmental evolution, the taste is very important, if very blunt nose, it is the possibility of more defective items ( Not all the tape) , then look at with tape down there is no back stick, did off residue after use, if the glue on the product, this is killed some of the defective tape. Adhesive tape PVC materials basically the same, basically be to see, the poor quality of the adhesive bandage after a period of time, to unlock, can see the glue and PVC material separation, looks sticky sticky, very not happy, and good quality tape will not appear this kind of problem.
