Is the Heat Shrinkable Tube just for sealing?

I believe everyone knows that the Heat Shrinkable Tube is a Heat Shrinkable Tube made of Cable Sleeve material, which is used in crisper boxes, lunch boxes, heat preservation boxes, pressure cookers and other fields. Needless to say, as soon as you hear the name, you know that it has a sealing effect. Now let's consider a question, is the Heat Shrinkable Tube only for sealing?

In fact, it is not. The Heat Shrinkable Tube has a wide range of uses and a wide range of effects. The main points are as follows:
1. Very good fresh-keeping effect. It can keep food or other items that need to be kept fresh to a very good degree. Moreover, the Heat Shrinkable Tube will not produce any harmful substances, and it is a completely non-toxic, harmless, green, healthy and environmentally friendly product.
2. High-quality sealing performance, can achieve complete sealing, and will not let a drop of water enter the sealed space.
3. The Heat Shrinkable Tube is also very adaptable to the environment. After it can be placed under a strong temperature for heating, it can keep its original shape and state well without deformation, and it can withstand high temperature. There will not be any harmful substances in the environment.
4. The performance of tensile force is good, and it can achieve the effect of not breaking or deforming under very strong pulling force.
5. Compared with other products of the same type, its color will not change, yellow or fade after long-term use.
6. Very good corona resistance, arc resistance, high temperature and low temperature resistance, in addition, the Heat Shrinkable Tube also has good aging resistance.
7. It has better elasticity than ordinary rubber, and can maintain better elasticity even at minus sixty or seventy degrees.
8. However, Heat Shrinkable Tube cannot be used in solvents and oils that have most of the shrinkage, or acids and sodium hydroxide that have shrinkage.
9. Very good electrical insulation performance, even under high temperature conditions, it will not be affected in any way.
