Heat shrink tubing is a tubular product, which is a ring-shaped object with peripheral interconnections. This is because when some users choose heat shrink tubing, they only measure the outer diameter of the product that needs to be protected and ignore the joints at both ends, resulting in heat shrinkage. If the shrink tube cannot be put in, it will appear that cutting the heat shrink tube from the side, wrapping it directly outside the wire, and then shrinking it can also achieve the same insulation protection effect? Can it still shrink after cutting? Today, the editor of DUWAI heat shrink tube will give you a practical verification on this issue.

First, let me show you what normal heat shrink tubing looks like after shrinking.

    The heat shrinkable tube also has the function of shrinking after being cut, but after shrinking, the opening position is uneven and the overall shape is not straight enough. As shown in the picture, after the heat shrinkable tube is completely shrunk after being cut, the opening will be misaligned and the opening will be relatively large. It completely fails to achieve the effect of protective insulation. Although it can shrink, its use is not recommended.

    Some friends may wonder whether the heat shrink tube will stick together after being cut and reheated? Due to the high temperature resistance of heat shrink tubing, the heat shrink tubing will return to its extruded state when heated. The cut heat shrink tubing will still have a tubular shape after shrinking, but the opening cannot be repaired. As a heat shrink tubing manufacturer, we can be responsible Let me tell you that the heat shrink tube will not stick together after being cut and reheated.

    To sum up, the heat shrinkable tube also has the function of shrinking after being cut. The heat shrinkable tube can be heated and shrunk after being cut, but it cannot achieve the effect of protection and insulation. The main function of the heat shrinkable tube is for insulation and protection. It is sealed and waterproof. Since there is an opening, it cannot provide insulation protection. Therefore, the conclusion is: the heat shrinkable tube can still shrink when exposed to heat after being cut. However, for safety reasons, please do not use it. We will judge the heat shrinkable tube after cutting it. Discarded, heat shrink tubing is very cheap. It is recommended to purchase heat shrink tubing with a larger inner diameter and larger shrink ratio.

    If there are occasions where cutting is necessary, such as quick repair of cables, DUWAI recommends zipper-type heat shrink tubes, also called cable repair patches, which can be opened from the side and then fixed with a buckle, still in the shape of a tube. Heat shrink tubing can effectively seal, insulate and prevent moisture.
