PVC electrical tape is soft polyvinyl chloride (PVC) film as substrate, coated with rubber pressure-sensitive adhesive. They have good insulation characteristics, cold resistance, refractory voltage, suitable for vehicle wiring, insulation protection, wire winding, etc.. PVC electrical tape, also known as the Myra tape is made of polyester film and solvent adhesive, tensile strength, high temperature resistance, used in the manufacture of a variety of Transformers. Ordinary smooth surface or fog surface insulation tape, adhesive, flexible material.PVC color tape is not monotonous. Red, blue, green, white, black and yellow. The flammability of PVC electrical tape

Buy PVC take note of the appearance of electrical tape tape. Mainly to see whether the baking section should be flat, no glue or cement. Although the PVC electrical tape with insulating performance, but different manufacturing processes can lead to different insulation performance. For example, add a large number of filling materials PVC material, anti white phenomenon will be elongated, and its insulation performance decreased a lot. After a double strength, no obvious white people, can see the material is still very strong. PVC electrical tape products lead is a frequently mentioned problem, PVC electrical tape is environmental security.

The flammability of PVC electrical tape

The combustion test of PVC electrical tape is a kind of special pressure sensitive tape / pressure design of flammability test. The test sample is a specific length with tape around a diameter of 1/8 inch steel rod, the top banner. The steel bar firing 20 degrees every 5 times (every 15 seconds) of the flame, the ignition time of the sample should not exceed 60 seconds, or indicating the degree of damage should not exceed 1/4. PVC belt type combustion test is a "pass / fail" height. UL approved or listed, and the "flame" certification tape, passed the preliminary test and UL test Follow-Up Services audit.
