The difference between heat shrinking tube and cold shrinking tube

Scope of application

Heat-shrinking tube and cold-shrinking tube are relatively common in the market. If you have used friends, you should be able to use more heat-shrinking tubes. As long as you need protection, you can use them, as large as military enterprises, aircraft tanks, ships. Metro high-speed rail and cars have applications, small household appliances, mobile phone charging lines and earrings, etc., some see, some hidden in the equipment can not see it, but the heat shrinking tube is real can not be ignored;

The cold-shrinking tube has a relatively narrower use range for the heat-shrinking tube, and the function is not as strong as the heat-shrinking tube, but it is used in the communication industry, but other insulating materials cannot be compared;

Advantages of heat shrinking tube:

1. The heat shrinking tube and the cold shrinking tube have different use principles. The heat shrinking tube is the principle of radiation expansion, and the cold shrinking tube is the natural expansion principle of the steel wire. The heat shrinking tube is a chemical reaction, and the cold shrinking tube is a physical reaction;

2. Compared with the heat-shrinking tube of almost the same specification, the heat-shrinking tube is cheaper because the raw material is cheaper;

3, the use of heat shrinking tubes is wider, and the application is more common;

4. Poor cold-shrinking tubes may be in a state of high temperature or low temperature in the transportation, and the heat-shrinking tubes do not have such a risk. The biggest risk is that the temperature may be greater than 70 degrees or more.

5, heat shrinking tube materials are more, there are silicone rubber, polyethylene, PVC, Teflon, fluorine rubber, etc., and the cold shrinking tube is currently made of silicone rubber material and EPDM EPDM;

Advantages of cold shrinking tube

The biggest advantage of the cold shrinking tube is that it does not need heat and shrinkage, no need to fire, and has an absolute advantage in working at height. Because of its special principle, it is very suitable for outdoor use and is widely used in domestic mobile, Unicom and telecom tower feeders. Anti-aging, anti-corrosion, anti-ultraviolet radiation, and excellent waterproof performance. If you are worried about waterproofing, there is a built-in double-melt cold-shrinking tube. The waterproof performance can be said to be icing on the cake;
