Overall, the use of double wall heat shrink tubing is relatively simple. Next, we will introduce how to use double wall heat shrink tubing correctly and other common problems.

1、 How to use double wall heat shrink tubing

1. The double wall heat shrinkable tube can be heated and shrunk with Alcohol burner, industrial Heat gun, industrial Heat gun compressed air and other heating tools for less shrinkage;

2. Double wall heat shrink tubes have a large amount of shrinkage, which can be heated and shrunk using tools such as water boiling, steam heating, ovens, conveyor belts, drying rooms, and shrinking machines;

3. The use of double wall heat shrink tubing is very simple, usually it can be heated by covering it well. For example, in normal use, we can use the hot air of an electric hair dryer to heat it, but it is important to note that the double wall heat shrink tube should not be too thick and there is no need to use adhesive tape inside. But be careful not to let the wire end pierce the double wall heat shrink tube, and if necessary, cover it with another layer;

Sometimes, someone uses a lighter to heat and ignite the lighter. They place a double wall heat shrink tube into the flame, and the flame swings back and forth along the axis of the tube for 2 to 3 seconds. If the double wall heat shrink tube is thicker or longer, it is necessary to extend the baking time as appropriate. Actually, there is no skill to speak of, just try and know, as long as you don't burn it.

2、 Common problems with double wall heat shrink tubing

1. What are the characteristics of the double wall heat shrinkable tube? The double wall heat shrinkable tube is a special Heat-shrink tubing made of polyolefin material. Generally, it shrinks when heated 125 °. The heat shrinkable sleeve is a special Heat-shrink tubing made of polyolefin and can also be made of EVA;

2. What are the materials and types of double wall heat shrink pipes? The main materials of double wall heat shrink pipes are PE, PVC, PET, ABS, EVA, etc;

3. What are the functions of double wall heat shrink tubes? Double wall heat shrink tubes are used for packaging and insulation of 18650 batteries, power batteries, electronics, inductance components, electrical appliances, wiring harnesses, pipe fittings, and other materials. By using a shrink machine or hot air blower, the double wall heat shrink tube can be tightly wrapped, providing insulation, protection, and other functions;

4. How to use double wall heat shrink tubing correctly: pre install the double wall heat shrink tubing onto the busbar, install all components, tighten the screws, lay the double wall heat shrink tubing flat, place it in an appropriate position, and use a hot air heater to heat shrink the heat shrink tubing onto the busbar;

5. Application scope of double wall heat shrink tubing: Double wall heat shrink tubing is now widely used for insulation protection of various 18650 batteries, power batteries, wiring harnesses, inductance components, and welding points, as well as rust and corrosion prevention of expansion rods, metal pipes, and rods;

6. What is the heating method for double wall heat shrink tubing? Common heating equipment can use hair dryers, hot air blowers, heat shrink machines, or high-temperature electric furnaces.

There are no tricks to use double wall heat shrink tubing. As long as everyone knows how to operate it, they will definitely be able to use it correctly. In addition, it is important to keep away from yourself when using a series of dangerous products such as lighters, and be careful when using them to avoid burns. In addition, there are many models and specifications of double wall heat shrink tubes available on the market, reminding consumers to clarify the range of products they use before purchasing.
