believes everyone not unfamiliar, heat shrinkable tube cold tube a lot of people are still not clear what is it about, actually cold tube is named relative to the heat shrinkable tube, heat shrinkage tube is called heat shrinkable tube, don't need to be heated draw support article can narrow tubes is called cold tube, today will bring you a look at the origins of the cold tube and development.

cold materials technology in the mid - 1960 - s produced by the invention, the first is not applied in the field, too deep into work until the late 80 s, in North America, applying cold technology to try to cable connector. But limited to the time of the materials technology, contraction speed slow, permanent deformation is large, the storage period is short, so bring inconvenience in practical application. In the 90 s, with the development of rubber technology and makes unified, materials and technology have played a rubber materials of excellent performance.

cold material mainly has three technology development process, developing alternate:

1, the expansion of technology: experienced - wire expansion - - - - - - - - - - - - Hop-pocket expansion - - - - - - - - - - - - - Without wire cloth bag expansion.

2, support materials, has experienced the spiral pipe welding nylon - - - - - - - - - - - - - Welding polyethylene pipe - helix - - - - - - - - - - - - The spiral pipe welding polypropylene.

3, materials technology, through the ordinary rubber - - - - - - - - - - - - - Heat shrinkable elastomer - - - - - - - - - - - - - Ethylene propylene rubber - - - - - - - - - - - - - Silicone rubber phase, the development trend of materials for solid silicone rubber - in the future - - - - - - - - - - - - Liquid silicone rubber - - - - - - - - - - - - - Mainly consists of liquid silicone rubber and the application in the field of fluorine material to meet the special requirements.

cold products to enter the Chinese market in 1994, the original is affected by the limelight strong heat shrinkable products, has not been recognized by the market. 2000 years later, with the obvious advantages of cold material technology, the market began to rapid growth, become customers of the most popular new technology products.

at present, the domestic cold material technology belongs to the fledgling stage, facing the huge market opportunities, develop products suitable for domestic use cold material, used to replace imported products is of great significance.
