Insulating tape: types and applications. How to insulate wires with electrical tape or heat shrink tubing Vinyl electrical tape

Use colored duct tape when tagging something in the system or when marking boxes when you move. Unlike stickers, it will not peel off, tear or fail.

2. Fix the binding

When the binding is frayed or the cover is torn, and the book is still read and read, seal the damage with a wide electrical tape. Attach the tape to the entire spine at once, fix it around the edges, or even wrap the entire cover with strips of strong adhesive tape.

3. Make a neckline

Insulating tape is the secret of a seductive neckline and generally revealing outfits. Yes, we are talking about Kim Kardashian and her duct tape bra (does not hold so well, falls off).

4. Protect surfaces when painting

When you paint something and it is very important that the drops of paint do not fall down and do not spoil some part (baseboard, visor, window sill), just seal this part with electrical tape. Then remove it along with the paint.

5. Make an airtight package

Any package becomes airtight if you have electrical tape. Just glue all the seams and joints with it additionally.

6. Fix the tent

There is no better material in the world for a quick tent repair than duct tape. In the place where the patch will be, the camphouse will be stronger than in all the others.

Also, tape must be put in a backpack if you went on a kayaking or cycling trip. As a temporary measure to seal a tire or boat, that's it.

Insulating tape works in general everywhere and everywhere. Electrical tape is a gift from the gods, it must be worshipped.

Andy Weir, The Martian.

Electrical tape will even help to hide from: if you wrap her legs in the place where the pants end and the socks begin, then the ticks will not have a chance to get under the clothes.

7. Make a bottle cap

Another reason to always carry at least a small roll of duct tape in your bag. You have a bottle of water but no lid. Wrap the throat with electrical tape more tightly, then hold out even without a lid.

8. Make a strap

When you need to move a box or some kind of cargo that does not fit in a bag or bag, and it is inconvenient to carry it in your hands, wrap it with electrical tape and make straps and handles out of it, like a bag. To do this, you need to fold the electrical tape in two layers, sticky surface inside, and make a loop of the desired length. The insulating tape is strong, withstands heavy loads and does not slip. And if you use a wide electrical tape, then the strap will be comfortable and will not cut your arms and shoulders.

9. Organize a playground

For example, you are at home, you cannot go outside (rain, hail, flood), and the child needs to jump into hopscotch, draw a railway on the floor or something like that. Mark up with tape. On it, the child will not slip, then you remove it, and the floor will remain intact. Tape will work on carpet too.

10. Fix the mat

Double-sided electrical tape will hold the rug at the front door or the path in the corridor so that no one accidentally slips on the carpet that has left from under their feet. This is especially true when there are children at home.

11. Make a rope

In general, electrical tape turns into a rope for anything. Two layers glued together, strong enough to hang clothes on. And if you weave a pigtail out of three such ropes, then it will withstand heavy loads. It can come in handy in any situation.

12. Help the person

Insulating tape is the means of the first. She is temporarily repairing objects and people. For example, a tourniquet, a pressure bandage, a tire will turn out from electrical tape. And she will replace the band-aid in extreme situations. And the electrical tape is indispensable if the lung is injured and you need to urgently apply a bandage that will not let air into the chest.

And with the help of electrical tape, splinters are removed. Only for this it is necessary that the splinter does not completely go under the skin.

13. Decorate the room

Any electrical tape is a material for creativity. A black tape that sticks to all surfaces is a designer's dream. She can draw almost anything on the walls.

14. Save yourself from the cold

Insulating tape also protects from cold air. If you get cold in an emergency, wrap yourself with electrical tape over your clothes. So you keep the heat from the body and do not let the cold air inside.

15. Mark the road

If you are walking an unfamiliar route far from civilization, mark the path with two strips of colored electrical tape. When you return, remove one strip at a time so as not to get lost and not go in circles.

What is insulating tape? First of all, it is a tape used for electrical insulation of wires and cables. There are about ten types of insulating tapes: fiberglass, polyester, mica, paper, PVC, acetate and several other options.

Polyvinylchloride insulating tape has been widely used. It is made of two materials: 1. PVC film; 2. adhesive layer. For better manufacturing, class A PVC film (the highest class of film) is used. The adhesive layer is the main component of the electrical tape, because it must be kept even after work in operation. Glue is selected on a rubber or acrylic basis. PVC electrical tape has the ability to stretch to 100% of its length, but due to this quality, it begins to lose its insulating characteristics. It is because of this shortcoming that several layers of film are applied. PVC electrical tape is made in different colors, but the most common are black, red and blue. Used for insulation of wires and cables.

Our production:

Also widely used cotton insulating tape. Its manufacture is similar to PVC tape. The rubber mixture of glue (overshoe pad, coarse calico) is applied to cotton fabric.

Cotton tape is of two types:

• Unilateral. The glue is applied to one side of the cotton fabric.
• Double-sided. Glue is applied to both sides of the cotton fabric.

Electrical tape is used at voltages up to 1000V. Insulating tape is used for winding wires and cables.

Fiberglass insulating tape is used up to 600 V. It is durable and resistant to high temperatures, which makes it possible to use it for winding wires in ovens, electric stoves; does not have the property of decay and burning. Compared to PVC and cotton tape, it is a bit difficult to make. Before applying glue to the fiberglass, it is treated so that in the future it does not form traces of corrosion. Glue is used rubber or silicone, they are sensitive to pressure, which is very important for fiberglass electrical tape.

The insulating tape must be produced according to a special GOST. The tape must be free of technical errors, such as bubbles, cracks, folds, uneven adhesive layer, otherwise the electrical tape will lose its quality.
In the Promresurservis company you can buy fiberglass in Moscow at retail and wholesale at manufacturer's prices, ordering the right amount of material for personal or industrial needs.

It would seem, what is easier? I unwound it, tore it off and glued it, but ... There are nuances even in using electrical tape, otherwise the electrical tape may soon begin to peel off, creating a risk of a short circuit.

Insulators are different. In principle, a machine is not a transformer substation, and any electrical tape can be taken according to electrical characteristics. But not every electrical tape can work in heat, dust, oil, dirt and other automotive conditions. Regardless of the type of electrical tape, there are general rules that will extend its life and increase efficiency.

Rule number 1: You can not touch the adhesive layer of electrical tape with your fingers.

Even on seemingly clean fingers, natural natural fat will definitely be present. And while working on a car, hands are never clean. If during wrapping, for example, twisting wires with electrical tape, touch its sticky layer, then the adhesive properties of this layer will decrease. This is especially important for the tip of the electrical tape, which, being dirty, unwinds over time and hangs. This is less critical for specially automotive electrical tape, but you still should not neglect the rule.

Rule number 2: Do not tear off the tape with your hands

This rule follows from the first. Very often, in the process of work, the desired piece of electrical tape is simply torn off from the skein. At the same time, one hand holds a skein, and the second - the same tip, which is better not to touch. To prevent this from happening, it is better to cut off the electrical tape with scissors, after wrapping the place of insulation or determining the required length of the tape section in advance.

Rule number 3: Electrical tape must be immediately glued to the right place

Quite often, insulating tapes arrange "gluing". That is, a sticker first in one place, then tear off and a sticker in another place. If the adhesive layer of the electrical tape is of high quality, then such a transfer may not affect its service life. But this is not always the case. Most often, after peeling off the tape, it will no longer stick in another place as well as in the first one. Therefore, it is better to immediately correctly determine the place for the sticker, and if the tape is unwound, replace it with a new cut strip.

Rule number 4: Tape must be glued tightly

Electrical tape, as well as, for example, wallpaper, must be glued without "bubbles". That is, ideally, a strip of electrical tape should wrap around the wire connection as tightly as possible. If the winding is too loose, moisture can get under the electrical tape and lead to oxidation of the wires. In addition, loosely wound electrical tape will take up a lot of space and rub against adjacent wires.

In order to tightly wind the electrical tape on the wire and at the same time not touch its adhesive layer with your hands, it is worth winding it directly from the skein. This is not always possible, sometimes there is simply not enough space. But if there is a place, then it is advisable to glue the edge of the electrical tape to the wire and wrap it around, holding a roll of electrical tape in your hand. In this case, it is necessary to cut off the tape when the entire required area is wrapped.

Also, for very important connections, it is advisable.

Insulating tape is a useful and indispensable material used for repair, household and other work. With its simplicity and ease of use, it has several characteristics and properties that must be taken into account during the purchase.

Types of insulating tape

There are two types of insulating tape:

• Polyvinyl chloride (PVC).

• Cotton (C/B).

PVC insulation tape is made from polyvinyl chloride. It is widespread, unlike cotton tape. PVC tape is produced in various colors. The most popular colors are: black, blue, red. The adhesive part of the PVC tape consists of a rubber or acrylic adhesive coating without toxic harmful substances, which makes it safe for human use.

Cotton tape is made from cotton fabric, coarse calico and other materials. The main advantage of cotton electrical tape is the fact that it can quickly harden when in contact with a heated surface. It is recommended to use cotton tape for insulating wires of electric stoves, ovens, heating elements, and other heating electrical devices.

Cotton insulating tape creates insulation, protecting against voltage up to 1000 V. It retains its operational properties at a temperature of -30 +30 degrees. This type of electrical tape has not found wide application, compared with PVC electrical tape.

Peculiarities

With the help of PVC electrical tape, it is possible to achieve tightness of the joint of various joints during technical, electrical installation, repair work, and protection from various factors. The use of such insulation is recommended for isolating live parts and, which is protection against touch and electric shock.

Basic properties

PVC tape has the following characteristics:

• Width 13-20 mm.
• Thickness 0.13 mm or more. As the thickness increases, its insulation properties increase.
• Increased breakdown voltage. Some manufacturers give a guarantee for the high values ​​​​of the dielectric properties of the insulating tape.
• High quality insulation is achieved by winding several layers of tape.
• The tape is resistant to heat, so it is used in a wide range of temperatures.
• Excellent adhesion is created by a combination of thickness and type of adhesive layer.
• Strength. Good strength indicators make it possible to use the tape for electrical work of particular complexity.
• Fire resistance. Tape is used to insulate wire connections, so this property plays an important role.

Advantages and disadvantages

PVC insulating tape has the properties of a dielectric, can create tightness, has good extensibility.

However, at elevated temperatures, PVC tape is prone to melting, so it is used in places that exclude heat. When choosing such a material, it is necessary to take into account the voltage, temperature and humidity of the place of insulation, as well as the temperature of the external environment.

Material Features

The composition of PVC electrical tape is based on polyvinyl chloride, the products are produced in rolls up to 19 mm wide. The material of the tape has good performance properties, it is used for insulation, fasteners, packaging and other works.

Tapes with an acrylic tack coat develop adhesion over time, while the rubber tack shows its tack immediately upon application. A feature of such an insulating tape can be called difficult flammability, explosion safety. However, if the tape does catch fire, then toxic substances are formed that are harmful to humans.

The insulating properties of the tape make it possible to use it in places with voltages up to 5000 V. This is enough for domestic and industrial use. The standard PVC insulation tape according to GOST 16214 - 86 has gained popularity in the insulation of cables, wires, pipes.

For the correct use of the tape, it is necessary to know the methods of application: during the insulation of the junction of the wires, the tape is wound, starting from a thinner place to a thicker one. With special care, you need to approach the bare places of the wires, while not pulling the electrical tape too much, as it may break.

The PVC tape is equipped with a sticky layer that has protective properties. When taping the pipeline with an adhesive layer, the surface of the pipes is protected from rust, since the adhesive layer insulates and protects the coating of the pipes. To ensure effective and high-quality sealing, the tape should be free of tears, defects and missing places of the sticky layer. Most often, the adhesive composition is based on rubber with the addition of a plasticizer, which is designed to create a tape resistance to environmental factors, including low temperatures and humidity.

High-quality PVC tape should be smooth, elastic, securely fixed to the surface. High stickiness guarantees its fixation on any surfaces of complex shape.

Application

PVC electrical tape is inherently universal, so it is used in different areas. The temperature range for using the tape is 0-90 degrees. It is used outdoors and indoors. In the trading network, the tape has a wide range of colors. High-quality electrical tape should not have an unpleasant odor, otherwise we can conclude that the material is of poor quality.

If the surface is destroyed, has pores and other damage, then before applying the PVC tape, the surface is put in order, treated with a primer. The tape should only be applied to a prepared, dry and clean surface.

PVC-based electrical tape is used in many areas:

• In the production of work with electrical engineering. In this case, such material is used to insulate electrical cables, wire connections during repair work, and mark wire harnesses.
• In household work around the house of various types, when repairing various things, tools and other household trifles.
• When repairing a car to insulate wires and other places.
• In the packaging of goods. The special adhesive-coated packaging tape is widely used for packaging light weight boxes. Packing can be carried out both manually and automatically.
• PVC electrical tape can also be used to repair boats using a special reinforced tape.

Pipeline protection

Let's take a closer look at the use of PVC electrical tape to protect pipelines. Much attention is paid to this protection, since the reliability of the pipeline and the entire system depends on it. Pipes laid in the ground are under the influence of the negative influences of the soil. Therefore, pipelines must be reliably protected.

For this, PVC tape is often used, which protects the outer surface of the pipe from corrosion. But for high-quality protection, the tape must be wound correctly. The tape is wound in a spiral, with an adhesive layer to the surface of the pipe. This makes it possible to avoid distortions and wrinkles on the tape.

Benefits of insulating PVC pipes with tape

• The tape is resistant to moisture, which allows for complete waterproofing.
• The tape material is not subject to corrosion and fungi.
• The adhesive layer provides high strength protection of the pipe with tape.

Insulating tape - This is the abbreviated name of the insulating tape, which is very well established in everyday life. From childhood, we all remember the blue rubber smooth tape, which was used to wrap all the bent wires in the house. Today, production has stepped far forward, and electrical tape on the market is presented in a great variety of types. Along with this, its technical and operational characteristics are improving, which both professional electricians and the common man should know about for using the product in everyday life.

Let's begin with thatinsulating tape is, first of all, a product for sealing and isolating various elements. Insulating tape is a consumable and serves to protect against external factors, which include moisture, sunlight, solvents, chemicals, etc. In the field of electrics, this is an excellent assistant in the electrical insulation of cable and wire products, as well as other conductive parts, which can cause serious harm to human health. Also, with the help of insulating tape, you can prevent the contact of bare wires with each other, avoiding a short circuit.

The most popular types of electrical tape that are used in everyday life arePVC tapes and HB tapes. That is, products based on polyvinyl chloride or cotton. Each type of electrical tape has its positive as well as negative characteristics.

PVC electrical tape is supplied to the market and to the end user in the form of a standard roll, the width of which varies from 14 to 19 millimeters. One side is covered with a special rubber or acrylic adhesive. These substances do not cause any harm to the human body, are not toxic and dangerous.

Regarding the technical properties, PVC electrical tape is resistant to high and low temperatures, which vary between -30° С and +50° C. One of the important characteristics isextensibility reaching 150%. This property greatly affects the reliability of the winding, as well as its impermeability.

Standard PVC insulation tape is capable of carrying voltages up to 5000V. This indicator is quite enough to use electrical tape both in everyday life and in production.

In order for the product you purchased to perform its functions efficiently, it must be properly stored. Storage of PVC tape should take place only in dry places where the presence of aggressive components is excluded, and the ambient temperature is between +5° - +35 ° С.

The most important advantage of PVC insulating tape is pleasant work, which consists in easy winding, high hermetic and dielectric qualities, does not smear hands, and stretches well. A minor drawback is that at too high temperatures it begins to melt, losing its high technical characteristics.

This type of insulating tape is very popular in practical applications. The product consists of a cotton base, which is carefully rubberized. The tape can have either one adhesive side or two. The fabric component is such materials as coarse calico, calico (hard calico), shoe lining, etc. In other words, a rough fabric base.

The temperature regime that the cotton tape is able to withstand falls into the range of -30° С - +30° C, and the dielectric and insulating abilities have a maximum value of 1000V. It is necessary to store HB-duct tape in a dry place at a temperature of 0 ° C - +24° C.

The main advantage regarding the application is the possibility of using in places with too high temperature conditions. Due to the fact that the fabric base is carefully rubberized, the properties are similar to PVC electrical tape. But when the cotton tape is fired, it acquires other qualities, while slightly losing the former. For example, HB-insulating tape can be used if it is necessary to insulate bare conductors heated up to 150 ° C. Firing produces a very hard coating instead of a simple fabric wrap. This coating guarantees good protection against direct short circuits. In this case, the isolated zone loses its resistance to high voltage values. This feature is very useful in heating equipment with heating elements (i.e. in places where there is low power).

The use of electrical tape does not end in the electrical field. This product is quite versatile as it has a simple flat band design which allows for wide application to many areas. This is what confirms the high significance of the product.
