PVC Tape is an economical material that is widely used in the insulation of various materials. Due to its simplicity and affordable price, it has found wide application in various fields. The first tape was created back in 1946 in the USA, after which it has been constantly improved and changed.

Features

PVC insulating tape ensures the tightness of the junction of different objects when engineering, repair or electrical work is carried out and protection from various factors is needed. The use of this material is useful when it is necessary to insulate current-carrying parts, bare wires, which serves as protection for people if they accidentally touch them.

Key Features

Modern PVC tape has the following characteristics: the width reaches from 13 to 20 mm with a thickness of at least 0.13 mm. Moreover, the thicker the tape, the higher will be its insulating properties. Important characteristics of electrical tape include:

1. High breakdown voltage. Many manufacturers specify high dielectric properties of the tapes, so they can withstand high voltages.
2. Guaranteed quality of electrical insulation is provided with insulation in two-three layers.
3. Due to a certain heat resistance, PVC tape can be used in a wide temperature range, up to extreme.
4. Good adhesion. It is provided by a thoughtful combination of thickness parameters with the type of adhesive layer.
5. Strength and breakdown voltage. Excellent performance allows the tape to be used in electrical work of any complexity.
6. Tensile strength. They help increase the elastic capacity of the tape.
7. Fire-fighting properties. Tape is often used in the processing of electrical wires, so it is important that there is no risk of fire or electric shock.

Dignity

PVC-based insulation tape has good sealing and dielectric properties and excellent stretchability. But at high temperatures, the tape may melt, so it will not work. When choosing this insulating material, one must proceed from the indicators of voltage, humidity, temperature of the object of insulation and ambient temperature.

Composition and features

PVC insulating tape is based on semi-vinyl chloride and comes in the form of a roll of tape, the width of which is 14-19 mm. Due to its excellent performance properties, the material is used in assembly, fastening, fixing, packaging and many other works. It is noteworthy that for tapes with an acrylic adhesive coating, adhesion becomes higher during operation, while the rubber coating shows its adhesive properties almost instantly. To featuresThis insulating material is explosion-proof and flame-retardant, but the tape may release toxic substances when burned.

Electrical insulating properties ensure the ability of the tape to withstand up to 5000 volts of voltage, which is quite enough for work in everyday life and at work. PVC tape (GOST 16214-86) is widely used when it is necessary to create insulation for wires, cables, pipes. In order for the material to perform its functions, it must be applied correctly: you need to wind it from the thin end to the thick one. Be especially careful to insulate bare wires, and do not need to tighten the tape too much.

Features of the sticky layer

Insulating tape has found wide application in various fields. Self-adhesive PVC tape has an adhesive layer that protects the outer surface of pipelines from corrosion, acting as an insulating and protective coating. The tape should not have defects, tears, gaps in the adhesive layer, so that the sealing is carried out as efficiently and effectively as possible. The adhesive composition in most cases has a rubber base, where a plasticizer is also added. Its task is to provide resistance to external influences, including humidity and temperature reduction.

A good tape should have a smooth surface, stretch well and be firmly fixed on the base. Increased stickiness ensures that the tape will be fixed on any surfaces.

Where does it apply?

PVC Tapewidely used:

1. When carrying out electrical work. In this case, this versatile material insulates wires, cables, when repairs are carried out, cables are marked and tied into bundles.
2. When carrying out household work for various purposes, when repairing kitchen utensils, tools and other small items is required.
3. For minor car repairs.
4. When packing goods. PVC based adhesive packing tape is widely used in manual or automatic sealing of medium-heavy boxes.
5. When repairing boats based on rubber, PVC reinforcing tape is widely used.

Special attention deserves the use of PVC tapes for pipelines.

Process Features

The protection of pipelines is given close attention, because the safety and reliability of the operation of the entire system depends on it. The metal laid underground is constantly under the influence of negative environmental factors, therefore, reliable protection of the line is required. For this, PVC pipe insulation tape is often used. Thanks to its unique properties, the outer surface is protected from corrosion, its insulation and reliable protection are carried out. But for this it is important that the tape is applied correctly. This is done as follows: the pipe is covered with adhesive material, and the work is carried out in a spiral. This will avoid the appearance of wrinkles or distortions. Pipe insulation with PVC tape is good for several reasons:

1. The material is highly resistant tomoisture absorption, so complete waterproofing is ensured.
2. The composition of the tape is resistant to fungus and corrosion.
3. Due to the sticky adhesive layer provides a high level of strength.

Providing electrical insulation

PVC Tape is versatile and can be used for a variety of purposes. The temperature range of application is from 0 to 90 degrees, and operation is possible both indoors and outdoors. Products are presented in a wide range of colors. It must be remembered that the insulating tape should not have a smell, otherwise it indicates poor quality.

Storage and recommendations

Insulating tape should be stored in closed warehouses, and you need to monitor the ambient temperature - from +5 to +36 degrees at a relative humidity of 80%. Do not use PVC tape in combination with organic solvents, chemicals, flammable liquids and aggressive media. Usage recommendations are as follows:

1. The temperature should be between 20-40 degrees.
2. PVC tape cannot be applied to silicone coatings or polymers containing fluorine. Deteriorating surfaces should be treated with primers.
3. Insulating tape is applied to the prepared surface, which will be thoroughly dried and free from contamination.

If the packaging, transportation and storage are correct, the electrical tape can be stored up to 10 years from the date ofproduction.
