Let's find out what types of electrical tape are, and what is its actual scope.
Types of electrical tape
The Russian industry produces the following types of insulating tape:
- Cotton (HB). It is, in fact, a rubberized cotton-based adhesive tape; can be either unilateral or bilateral. It has sufficiently high heat-resistant qualities - it can be operated at temperatures over 100 °C.
- Polyvinyl chloride (PVC). It is a PVC film with an adhesive composition applied on one side (rubber or acrylic adhesive). Such electrical tape is not as heat-resistant as cotton, but at the same time it has an important quality - it is an excellent dielectric and has high elasticity. High-quality PVC electrical tape is able to withstand voltages over 4000 V.
To ensure high quality electrical insulation, experts advise winding electrical tape in several layers, approximately 2-3.
The above types of tape cannot be called a quality standard: they lose their properties when the humidity rises, they can “peel off” in the cold, they are poorly unwound from the roll, the glue “flows” - it remains on the fingers and the lower layers of the tape, etc. The industry does not stand still, and electrical tapes produced by well-known European companies have truly unique properties, which we will discuss in more detail.

iso pvc tape is a demanded consumable, the most important purpose of which is to provide hermetic durable isolation of various objects and parts from certain factors environment.
What is electrical tape
PVC insulation tape has a standard spool shape with a width of approximately 14-19 mm. On one of its sides, a certain sticky coating of rubber and acrylic adhesive is applied. These substances are completely non-toxic, therefore they are completely harmless to humans. It should be noted that this material has good resistance to various kinds of temperature extremes. In addition, it has simply excellent extensibility. This quality, first of all, affects the winding itself and the impermeability during its application.
PVC electrical tape is a material made on the basis of polyvinyl chloride and designed to insulate wiring from such environmental factors as:
- Moisture;
- Sun rays;
- Solvents;
- Salt solutions.
In addition, it is used to isolate bare electrical wiring from accidental human contact with them or interaction with each other, which will prevent the likelihood of a short circuit. The most common are PVC-based tape and HB electrical tape.
The electrical tape is designed to withstand voltages up to 5000 volts, which is quite enough for use in industrial and domestic work.
To preserve the qualities of the material, it is recommended to store the electrical tape in a dry, not aggressive environment. This material is very practical and easy to use, as it is perfectly wound, has good hermetic abilities, and does not get dirty.
Features of HB electrical tape
HB insulating tape is a very popular material that is widely used in domestic conditions.
This is cotton rubber band made from materials such as:
- Calico;

- Shoe lining.
To ensure the most optimal storage conditions, the room temperature should be between 0 and 24 degrees. Relatively practical application This type of insulating tape has the advantage of being used in very hot places. Due to the fact that it is rubberized, it can be used in the same way as PVC. However, it is worth noting that it withstands a high melting point during firing, as a result of which, some qualities disappear from it, and completely different ones appear.
As a result, a hard and durable coating is formed in the winding area, which is able to protect bare areas from short circuits with conductive parts. Especially this quality is used in heating devices.
Insulating tape and its types
Insulating tape is one of the very useful materials used to insulate various objects and structures. This product has many varieties, each of which is used for different purposes and has its own specific qualities and characteristics.
