And they could match the long term operation demands of the electric power system. After the process of shrinking, heat shrink tubes can have arbitrary bending. And higher ability to stand tearing and wearing.
What is the using methods of heat shrink tube made by heat shrink tube manufacturers?
1. Prepare related materials. We need to have some knowledge of the cable’s diameter. Or we just do it according to the length and width to calculate the related diameter. Then choose the cable with bigger diameter than our heat shrinking tube.
2. Clean rags and sharp corners on the cables. So it is in case that these rags or sharp corners will impale heat shrink tube. It will result in cracks directly. So it is necessary to clean oil contamination, impurities on the connecting position of the cables.
3.Calculate the needed length for tube produced by the heat shrink tube manufacturer. Then cut the heat shrink tube with related length. During the cutting process, the incision cut should be tidy and smooth. It is without any cracks or rags. So it is in case of cracking extending.
4. Put the heat shrinking tube covering one cable end. Then move the tube to appropriate position. If the cable have some bending part, we need to neaten this part. It is in case of wrinkles.
5. The common tools for heating are heat guns, ovens, or hair drier. During the heating course, we should heat in one direction from left to right or right to left. Your can also start from the middle part to the two ends as well. It is in case that the air are left inside the tubes, after shrinking the air cover the cable in the tubes tightly.
In addition, it is not available to concentrate to heat at one position. And it is not okay to heat the close to the surface of the tubes. It is in case to hurt the tubes and result in wrinkles.
What is the attention tips for using heat shrink tube?
1. Don’t put the heating equipment close to the heat shrink tube produced by heat shrink tube manufacturers.
It is necessary to keep a distance from the fire to the heat shrink tube. It can be 4-5 cm to move evenly. When it is in the course of heating and shrinking, the temperature cannot higher than the maximum temperature.
If the temperature goes higher than the maximum limit, the tubes will start to melt. And the tube may turn back to the original state.
2. Choose an appropriate tool for heating.
The angle between the outer flame and the heat shrinking tube is suggested be 45. In addition, we should keep moving the heating tool during the whole heating course. So it can make the whole tube heated.
And when we move the heating tool, it is also very crucial to move in one direction from one end to the other end. Heat the tube evenly, no bubbles are required. It is to guarantee the pretty look of the outside appearance of the tube after the shrinking. Then make some tiny modification after it cools.
3. Heat shrink tube has various shrinking rates.
The specifications of heat shrinking tube are many. It usually mean the arithmetic products of the maximum inner diameter after the shrinking.
For example, the heat shrink ratio is 2:1. That means we can choose the heat shrinking sleeve’s diameter twice our product. If the diameter of the products is 20 mm, we could choose the heat shrink tube of 40 mm diameter. It offers strain relief for the users.
Sometimes, we will choose the outer diameter same with heat shrink tube made by heat shrink tube manufacturers. The protection of power system station need heat shrink tube. And the electric appliance cabinets also needs the professional heat shrink tube. And some fields with sealing requirements should choose water proof heat shrinkable tube.
How to tell the high quality heat shrink tube and bad one?
1. From the appearance of tube made by the heat shrink tube manufacturers.
Heat shrink tubes are smooth on the surface. It has leveling shape. There are no big or obvious wrinkles from the vision. We need to take a close view to find out if there is impurities or bubbles on the surface.
For adhesive heat shrink tube, we should watch if there is shedding phenomenon on the surface of the adhesive layer. And whether the color of hot melting adhesive turns yellow.
For the long stocking adhesive heat shrink tubes, they usually have yellow adhesive or adhesive shedding phenomenon.
2. From the thickness of the tube made by the heat shrink tube manufacturers.
It is better to measure if the thickness of the tube is even by vernier caliper. And if the tubes are qualified.
3. From the material of the tube made by the heat shrink tube manufacturers.
The material of heat shrink tube has decided the parameters of basic performance and characteristics.
P, PVC, EMDM, silicone rubber , PVDF PTFE are different in the raw materials. This will lead to different applications in the industry. For the common protection, insulation of the wiring cables. You are better choose our common PE heat shrink tube. It can hold it perfectly.
4. From the shrinking rate of the tube made by the heat shrink tube manufacturers.
We can try to cut one length of heat shrink tueb. And then heat and shrink it by lighter or some other kinds of heating tools.
Compare the shrinking rate and situations with other companies’ heat shrink tubes.
The ones which have higher quality and shrink completely are qualified products.
5. From anti-fire level of the tube made by the heat shrink tube manufacturers.
Just use the same method to ignite the heat shrink tube. And leave the fire after ignition. Compare different companies’ tubes’ time of being out automatically.
6. From hardness, tensile strength, voltage resistance of the tube made by the heat shrink tube manufacturers.
We can find all these parameters by buckling, tearing and etc.
Introduction to the Inner Diameter and the Wall Thickness of Double-wall Heat Shrink Tube
Here is PE double-wall heat shrinking sleeves’ parameters.
1. Inner diameter of double-wall heat shrink tube.
As we all know, the cross section of annular tube is cyclinder tubulous shape. Inner diameter means the diameter of inner wall. It is namely the direction between the inner wall.
Usually, we use the letter to represent. It is professionally to be the representative of diameter in the field of engineering. Number following means the diameter’s number value. If there is no units follow, it means the unit is millimetre. For example, 6 means that the inner diameter is 6 mm.
2. Wall thickness of double-wall heat shrink tube.
The second parameter is wall thickness of heat shrinking sleeve. The inner diameter can reflect the size of the tube. So what is wall thickness used for?Intuitively speaking, it is the reflection of the product. Is it thin or thick.
What is the influence of “thin and thick”? It is known that our heat shrinking tube is used for insulation. The issue of “thin and thick” will directly affect the function of insulating protection.
As We all know, thicker coat can offer higher resistance to cold and keep us warmer. If the coat is thinner, we will feel cold. And the coat’s function of resisting to cold decreases.
And the thickness of heat shrink tubes made by heat shrink tube manufacturer is the effect factor of the protection ability. Thus, in comprehensive opinion, thicker wall means the thicker the wall is. And it also owns the stronger mechanical ability the heat shrinking tube.
Applications Solutions of heat shrink tubes?

Q4: Customer has the requirement for cutting the tube. It is very important to have accurate calculation.
A4: Suggestions: 1. Calculate the size of cutting tube accurately. Then inform the customer the tolerance. 2. When the cutting requests for length is more than 30 mm. And the demand for stretching is very strict. It is necessary to mark for special manufacturing in the order.
Q5: Shrinking of products is not in complete place
A5: The size of drive pipe is too big. It is bigger than the customer required size after shrinking.
1. Use smaller size product to take the place of current one.
2. Use high shrinking rate product.
3. Rest without shrinking products, use low-temperature tubes. These shrinking temperature is low.
Q6: Drive pipe’s wall is too thick for shrinking. And the speed turns low.
A6: Suggested solution: Use high shrinking rate product. Super thin product of our company is also okay.
Q7 : Chromatic abberation in the product
A7: 1. Here is too many types of specifications and colors of heat shrinking tubes. The color is greatly affected by mixed master batch and the batch of raw materials.
2. There is different between high voltage busbar and low voltage busbar. It is because of different formula system. It will result in different colors oF heat shrinkable tubing. Different batches, different colors of heat shrink tubing manufacturers. It is because the raw material may not come from the same batch.
