Heat shrink tubing is also known as heat shrink sleeves. They play a very important role. First of all, you need to know that they consist of thin wires. They are made of materials that guarantee the resistance of the cable insulation to dust and dirt. Indeed, polyethylene also increases resistance to puncture.

What exactly is heat shrink insulation?
The use of heat shrink tubing strengthens the insulation. You can choose heat shrink sleeves with glue, which are widely used in the insulation of electrical wires. Each heat shrink tubing has a shape memory, provides good sealing against water and dust of all cable connections. Additionally, its parameters are so good that it also provides protection against extreme heat. The cables are waterproof and resistant to very high temperatures. Therefore, the heat shrink installation is primarily to provide proper protection and seal the connections or cable insulation.
Its use makes the cables resistant to chemicals. Of course, we must also mention that cables can be marked. Heat shrink insulation is used in industry. Heat guns are used to heat the heat shrink tubing of the cable, which speeds up the assembly of hydraulic or electronic installations. It is also worth knowing that if quick connectors with tin or thicker heat shrink tubing are used, then in such a case a gas burner is most often used to heat them.
What material are heat shrink tubing made of?
Heat shrink tubing called sleeves guarantee high durability. Additionally, protection of the installation wires is provided. It is important to know that the heat shrink sleeve can be with glue. The shrinkage coefficient also plays an important role. The question also arises - what material of sleeve should you choose? Those made of heat shrinkable polymers work best. These are special polymer substances that shrink under the influence of high temperature.
Importantly, one of the most popular materials used for production is polyethylene, which has many properties. First of all, it is characterized by low density, low abrasion, low water absorption, and dimensional stability. Additionally, the tubes gain greater mechanical resistance and excellent electrical insulating properties. Heat shrink tubing with glue protects primarily against water and moisture. This applies to all wires and cables that are used in places where there is a risk of water penetration and high humidity.
At what temperature do heat shrink tubing start to shrink?
Coated pipes in cable insulation are a form of protection. Every heat shrink pipe can shrink. Of course, it depends on the temperature. So, what temperature is needed for shrinkage to occur? It all depends on the type of material it is made of. Polyolefins, which are resistant to UV radiation, are most often used. The temperature at which the sleeve begins to shrink oscillates between 90 degrees and 135 degrees Celsius. When heating the sleeve, it is necessary to maintain an even temperature over the entire surface. This allows for the effect of optimal heat shrinkage. However, care must be taken to avoid overheating. In such a case, the material that has been overheated is damaged.
In which installations is it worth using heat shrink insulation?
The use of heat shrink tubing is really wide. First of all, they are used in the maintenance and maintenance of proper and correct operation of electronic devices. The sleeves can be used to create or repair installations on wires. They also allow for the creation of quick electrical connections. They also improve aesthetics. They provide protection for wires from adverse external factors. They are used to connect wires into bundles. The highest quality materials must be used already at the production stage. Thanks to this, each wire and tube is protected from dust and moisture.
Heat Shrink Insulation Installation: Step by Step
Installing heat shrink insulation is not difficult. First of all, you need to choose the right sleeve and select the diameter. It should match the protected elements. Then, you put the sleeve on the wire or other element. This means that it gains greater resistance. Then, the sleeve is heated. Lighters, heat guns or gas burners are used here. The material must shrink and until then, a heat gun is used. Once the sleeve is heated, you can move on to the last stage, which is cooling it. It is best to leave it to cool down, which will help maintain its shape and good properties.
