Good Insulation Performance
PVC itself has excellent electrical insulation properties and can effectively prevent the passage of electric current. The electrical tape made of it can be used to wrap wire joints and other parts, preventing electric leakage and short circuits and ensuring the safety of electrical equipment and personnel. Generally, it can withstand a certain voltage level, such as insulation protection for circuits up to 600V.

Fairly Good Heat Resistance
Ordinary PVC electrical insulation tapes have a certain heat resistance range. Usually, they can maintain good performance stability in an environment from -10°C to 60°C. Some heat - resistant PVC electrical insulation tapes processed by special formulas and techniques can withstand higher temperatures and meet the electrical insulation requirements in high - temperature environments, such as for wire insulation near ovens, heating equipment, etc.

Strong and Durable Adhesion
The pressure - sensitive adhesive used in this tape has good adhesion and can firmly stick to the surface of wires, cables and other objects without easy detachment. Moreover, during long - term use, the adhesion can remain stable. Even in different environmental conditions, such as humid and dusty environments, it can maintain a good sticking effect, ensuring the integrity of the insulation layer.

Excellent Flexibility
The PVC material has good flexibility, enabling the tape to be easily wound around wires and cables of various shapes and sizes. It can closely fit the surface of objects and will not break or lose adhesion due to operations such as bending and stretching, which is convenient for construction workers to operate and is suitable for various complex wiring environments.

Good Mechanical Properties
It has certain tensile and tear resistance. It is not easily damaged by external forces during use and can protect the internal wires and cables from external mechanical damage. For example, it can withstand the friction and pulling forces that may occur during the wiring process.

Good Chemical Corrosion Resistance
It has good tolerance to some common chemicals and is not easily eroded by chemicals such as acids, alkalis and oils. This makes it maintain stable performance in different chemical environments and extend its service life. It can be used in places with a risk of chemical corrosion, such as chemical workshops and laboratories.

Diverse in Color
It usually comes in a variety of colors, such as black, white, red, yellow, etc. Tapes of different colors can be used to distinguish different circuits or functions, which is convenient for installation and maintenance personnel to identify and operate. It improves work efficiency and accuracy and is conducive to the management and troubleshooting of electrical systems.

Low Cost
Compared with some high - performance insulation tapes, the production cost of PVC electrical insulation tapes is relatively low and the price is more affordable, with high cost - performance. Therefore, it is widely used in general electrical installation, maintenance and other fields and can meet the insulation requirements of most conventional electrical applications.
