We all know that both the cold shrinkage pipe and the heat shrinkage pipe belong to the insulating pipe. The cold shrinkage insulating pipe and the heat shrinkage insulating pipe are believed to have been known in the previous articles. So today we will talk about the difference between the cold shrinkage pipe and the heat shrinkage pipe.

The difference between cold shrinkage tube and heat shrinkage tube is that the use scope of cold shrinkage tube is relatively narrow for heat shrinkage tube, and its function is not as strong as that of heat shrinkage tube, but it can not be compared with other insulating materials in the communication industry.

The difference between cold shrinkage tube and heat shrinkage tube is as follows: 1. The use principle of heat shrinkage tube is different from that of heat shrinkage tube. Heat shrinkage tube is based on the principle of radiation expansion, while cold shrinkage tube is based on the principle of expansion support, heat shrinkage tube belongs to chemical reaction, and cold shrinkage tube belongs to physical reaction. 2. Heat-shrinkable pipes of similar specifications are cheaper than cold-shrinkable pipes because raw materials are relatively cheap. 3. Heat shrinkable pipes are widely used and widely used, mainly for wire connection, solder joint protection, wire harness at the end of the wire, protection of electronic devices and insulation treatment. 4. The cold-shrinkable pipes with poor quality may burst due to high or low temperature or turbulence in the transportation process, and the biggest risk of heat-shrinkable pipes is that the temperature may shrink above 70 degrees. 5. There are many materials for heat-shrinkable pipes, such as silicone rubber, polyethylene, PVC, ferrofluorone, fluororubber and so on. At present, only silicone rubber and EPDM are used for cold-shrinkable pipes.

The difference between cold shrinkage tube and heat shrinkage tube: the biggest advantage of cold shrinkage tube is that it does not need fire to heat and shrink. It has absolute advantage in working at high altitude. Because of its special principle, it is very suitable for outdoor use. It is widely used in domestic mobile, Unicom and telecommunication tower feeders. It has excellent aging, corrosion resistance, ultraviolet radiation resistance and waterproof performance. The heat-shrinkable pipe must be heated and contracted by means of heating tools.
