What is the boot tube?

The heat reduction coarse is a type of plastic tube whose diameter is reduced when heated. The materials used to produce thermal reduction change, but include complex polymers and similar materials. The thermal reduction of the hose is most often used in electrical applications to protect, insulate or repair wires, terminals and other types of electrical connections. It expands the life of these items and ensures their good performance. The tubes can be reduced specifically treated during the production process during heating. This type of tube is reportedly based on expansion. When it is made, it is heated at close to its melting point and stretched to expand its diameter. Then he cools down quickly to help him keep his shape. After warming up later when using consumers, the tube is reduced back to the size that was first stretched.

There is a certain proposal that the heat reduction tubes can be made by a process that includes a change in the chemical structure of the material itself. In tOmto tubing types with many monomers - individual molecules of a certain compound - when heated by the lines into the chains. This process is called polymerization. When monomers are more connected, the material decreases effectively. However, the difference in size before and after polymerization is not dramatic, so it seems likely that almost all heat boot tube is at least partially based on expansion.

Every kind of heat shrink pipes on the market has its own shrinkage ratio, which means to what extent it will shrink. For example, a tube with a shrinking ratio of two to one is reduced to half the original size. One that has six to one shrink dose is reduced to one sixth of their original size. The required shrinkage ratio will depend on the specific application of the tube. Heat shrinkage has a number of common uses, such as insulating outdoor wires and cables against elements, grouping multiple wires together and color coding of wires for easy identification.

Raychem CorporaTion was the developer of Heat Shrink Tubing at the age of 50. While all plastics are shrinking when heated, the company has developed a way to treat plastics to reduce, but not to melt or degrade, even at very high temperatures. They found that when some polymers are exposed to radiation, they develop stronger internal chemical bonds. This process has become known as the strengthening and gives the hose the ability to reduce its original dimensions and also gives it a very high strength and durability.
