Heat shrink tube can be used to heat and shrink the tool to protect the wire, and the shrink process is a gradual process. It takes a certain time to complete the shrinking.

Factors affecting the shrinking time of heat shrink tube, first point, we should think of the heating tools. If boiling in the water is compared with using heat gun, of course the later should be faster, because the temperature of the hot air gun rises faster, so choosing the right heating tool is one of the important reasons that affect the shrinking time. Commonly include lighters and hair dryers , oven, boiled water, hot air gun, etc.

Factors affecting the shrinking time of heat shrink tube, second point, depends on the size of heat shrink tube. The size of heat shrink tube includes the wall thickness, the size of the inner diameter, and the length of heat shrink tube. The smaller the tube, the faster it shrinks, the larger the specification, the thicker the wall thickness, the longer the contraction time.

An important factor affecting the shrinking time of the tube is also the material itself that constitutes the heat shrink tube. For example, heat shrink tube made of PVC and PE is shorter than that made of PVDF and PTFE under the same shrinking method.

To sum up, when the physical size, heating tools and other factors are the same, the shrinking time of the tube is affected by the using heating method and the builder's experience and skills. It should be noted that the factors that affect the shrinking are not absolute, and the appropriate heating tools and methods must also be selected according to the actual situation.
