Heat-shrinkable tubing is an insulating element used for cables. They are also used as markers due to the wide range of colors. They provide the cables with an additional protective layer in order to minimize the risk of undesirable effects on adverse external factors. When exposed to high temperatures, heat shrink tubing shrinks and thus adapts perfectly to the shape of the cable. The shape memory makes it possible for the tubes to shrink in any way. We can distinguish two dimensions of the tubing - the original size of the tubing and the extended size, i.e. the delivered dimensions. Heat shrink tubes come in many sizes and colors. They have a wide range of applications and are widely used in various industries as insulation, protection and sealing of cables. They are suitable for difficult environments, where there is a risk of contact with chemicals and water, and there is a clear and intense influence of atmospheric factors on electrical installations.
Heat shrink tube with a diameter of 2.4 mm. the Product is used to protect the wires by removing the insulation or close control of the brain active and not aging absorbed. Tube when heated, shrinks to a diameter of 1.2 mm.
This ser consists of 4 types of heat shrink solder connectors. The set includes the connectors with a diameter of 8 mm, 5 mm, 3 mm and 2 mm. Connectors shrink under the influence of heat. The set is enclosed in a small container.
Heat shrink tube with a diameter of 3.2 mm. The product achieves more than 50% shrinkage in the shrink temperature 90°C (approx. 1.6 mm). Heat shrink tubing have a universal application in isolation of compounds and electric wires, protection of soldering points, as well as to protect metal parts from corrosion.

Set of multicolored heat shrink tubing length 100 mm and diameter from 1.6 mm to 9.5 mm. The kit includes 170 pieces of tubes in 6 colors: red, blue, yellow, white, transparent and black. The tube type CB - HFT is flexible and resistant to ignition to 125°C. This product does not contain Halogens and is widely used in electronics, and second.
Heat shrink tubing is characterized by a simple design and construction. They are made of polyethylene, which is polymerized by ionizing radiation. The material shrinks under the influence of temperature in the range 20-70%, which depends on the size and thickness of the tube as well as its manufacturer. They are used to insulate electrical wires and connections between wires. They are also cable markers, so they come in many different colors. They are sometimes additional reinforcement for the insulation. Heat-shrinkable tubes also work well as connectors of two elements. They effectively protect metal elements against corrosion, which has a destructive effect on them, significantly shortening their durability.
When choosing shrink tubing, we always adjust it to the diameter of the tubing to be used. However, it is important to keep in mind the shrinkage of the tubing, which can be greater in some cases and much smaller in others. Usually the shrinkage is 50% (2:1). This means that it reduces its diameter twice after contact with high temperature. Shrink tubes differ in their resistance to extremely low and high temperatures. The range should be at least -30°C and +120°C. The larger the range, the better the effectiveness and resistance to possible damage due to welding on the wire. It is very important that shrink tubing is resistant to mechanical damage and has a high strength. They cannot be damaged by stretching and bending. There is another important value for the tubing - electrical puncture resistance. This must be at least 15 kV/mm. When marking cables, choose several colors for shrink tubing. It is best if they are in contrasting shades, which makes it much easier to distinguish between the individual wires. All available tubes are free of toxic substances such as lead and mercury. They pose a danger to the environment as well as to humans.
During the welding on the cable and during subsequent use, the operating temperature, which is always given by the manufacturer, must not be exceeded. If this rule is not observed, there is a high risk of damaging the pipe first and then the cable it covers. Too low a temperature in turn can lead to small cracks that weaken the structure of the tube. The shields should have a tensile strength, but we avoid stretching them above the values mentioned by the manufacturer. This does not always lead to destruction of the casing structure, but almost always results in its weakening.
