Nowadays, 4x heat shrinkable tube with glue has become a quite popular heat shrinkable tube. In fact, heat shrinkable tubes have a very wide range of applications in our life and work. With the continuous updating of society, there are quite a number of types and quantities of heat shrinkable tubes on the market. At the same time, it has many specifications, and each size of the heat shrinkable tube has a corresponding difference, and its function is also different. However, their principles are consistent, and they are all so-called "preheating is shrinking". What are the specifications of heat shrinkable sleeves? Therefore, next, Xiaobian will analyze its principle and specifications for you.

4X heat shrinkable tube with glue

Principle: under the action of high-energy rays, linear polymer materials form a three-dimensional network cross-linked structure. The crosslinked polymer material has been greatly improved in mechanical strength, temperature resistance, chemical solvent resistance, aging resistance and other aspects, especially in acid and alkaline resistance. At the same time, the heat shrinkable tube has the special function of shrinking in case of heat. It can shrink when heated above 98 ℃, which is convenient to use.

Heat shrinkable tubes can be divided into low-voltage (1KV) flame-retardant tubes, continuous long busbar tubes, high-voltage (10kV and 35kV) busbar tubes, etc. Among them, the size of flame-retardant burning tube is: Φ 1/0.5、 Φ 1.5/0.75..... Φ 180/90、 Φ Above 200; The size of busbar is from Φ Starting from 25 / 10, Φ 30/12…… Φ 200/60。 In addition, heat shrinkable tubes can also be divided into heat shrinkable tubes with glue and heat shrinkable tubes without glue. At present, four times of heat shrinkable tubes with glue are quite popular.
