Heat shrink tubing in practice   

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. 

Heat shrink tubing in many options 

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.
