What's the difference between a cold shrinkable tube and a heat shrinkable tube? Is there anything better than this?

Heat shrinkable tubes and cold shrinkable tubes are very common in the market. If used friends can use heat shrinkable tubes in many places, as long as they need protection, from military enterprises, aircraft tanks, ships, subways, high-speed rail, cars, to household appliances, mobile phone charging lines, earrings, some are visible, some are hidden in equipment, but heat shrinkable tubes are real and cannot be ignored.

Methods/steps

The application scope of cold shrinkable tube is relatively narrow for heat shrinkable tube, and its function is not as powerful as that of heat shrinkable tube, but it is incomparable to other insulating materials when used in communication industry.

1, the use principle of heat shrinkable tube and cold shrinkable tube is different, heat shrinkable tube is radiation expansion principle, while cold shrinkable tube is natural expansion principle of steel wire, heat shrinkable tube is chemical reaction and cold shrinkable tube is physical reaction;

2. Compared with the cold shrinkable tube, the price of the heat shrinkable tube with similar specifications is lower because the raw materials are cheaper;

3. The heat shrinkable tube has a wide range of uses and is more widely used;

4. Poor cold-shrinkable tubes may burst due to high or low temperature or bumps in the environment during transportation, while heat-shrinkable tubes have no such risk. The biggest risk is that they may shrink at temperatures above 70 degrees.

5. There are many materials for heat shrinkable tubes, such as silicone rubber, polyethylene, PVC, Teflon and fluororubber. At present, the cold shrinkable tube is made of silicone rubber and EPDM.

The biggest advantage of cold shrinkage casing is that it does not need heating shrinkage and hot work. There is an absolute advantage in aerial work. Because of its special principle, it is very suitable for outdoor use. Widely used in domestic mobile, China Unicom, telecommunications tower feeder, with excellent aging resistance, corrosion resistance, ultraviolet radiation resistance, waterproof performance. If you are worried about waterproofing, there is also a built-in double mortar cold shrinkage pipe, which can be said to be the icing on the cake.

Matters needing attention

Select the appropriate insulating tube according to the actual needs.

Secondly, pay attention to the correct method when heating or drawing. Proper operation will prolong the service life for several years.
