How to choose PVC electrical tape

PVC electrical tape is made of soft polyvinyl chloride film and coated with a specific pressure-sensitive adhesive. It is often used for insulation wrapping, bundling and fixing of wire and cable joints, and insulation protection of motor electronic parts. When purchasing electrical tape, do not ignore the quality for the sake of cheapness. Poor quality electrical tape is prone to overflow and dislocation over time, or when the electrical appliance is overloaded and the joints are heated, the hot zone melts and shrinks... These hidden dangers are likely to cause line abnormalities, or even short circuits and fires, directly endangering personal safety. Only by choosing high-quality, safe and stable performance products can you ensure the safety of yourself and others and achieve good construction results.

Tips for testing the quality of electrical tape:

1. Touch method: Gently touch the adhesive surface of the tape with your hand and then quickly remove it. Generally, the stronger the adhesive force, the better the adhesion.

2. Pulling method: Repeatedly pull the rubber surface, with strong force and no debonding, good adhesion and good quality.

3. Stretching method: Stretch by hand. For tapes of the same thickness and width, the ones with greater force and longer elongation are of good quality. The ones that break easily are recycled materials and of poor quality.

4. Simple test method for flame retardancy: After igniting the tape with a lighter, remove the lighter, and if the burning length is within 15cm, it is flame retardant.

5. Smell method: After unwinding the PVC tape, smell the tape with your nose. If the smell is strong (pungent) or smells bad, it means that the tape is of poor quality.
