What is heat shrink tubing?

Heat shrink tubingHeat shrink tubing is exactly what its name indicates: it is tubing that shrinks when heat is applied. It can be used for a wide range of purposes and can be helpful for doing both preventative maintenance and making repairs. Heat shrink tubing can be used many different ways. Common preventative maintenance applications include relieving strain, providing additional insulation, and sealing the cable. Not only can heat shrink tubing provide additional strain relief, but it can also provide extra insulation. Heat shrink tubing has great electrical qualities which makes it ideal for use with connections, terminations, and circuit board applications requiring additional environmental and electrical protection.

Moreover, heat shrink tubing can be utilized in many preventative maintenance applications, it can also be extremely helpful when making repairs. Whether the fixes are temporary or permanent, it can be used to cover damaged cable jackets, insulation, connections, or cable splices. It makes for a quick and easy fix while you wait for the cable to be replaced, but it also works effectively enough to serve as a permanent repair in some cases. After that, heat shrink tubing is available in a wide variety of colors and can be printed with permanent labels, so marking circuits is simple.

There are several factors to consider when choosing heat shrink tubing. Beyond the usual considerations of temperature and voltage ratings, environmental hazards, and other application requirements involved in choosing cable products, heat shrink tubing requires attention to a few more details. First are sizing requirements necessary to ensure that the heat shrink will fit snugly in its application and work the most effectively. The sleeve diameter is crucial in heat shrink tubing. The tubing must be large enough in its original state to fit over any large or irregular surfaces, but it must also have a final diameter small enough to ensure that it will shrink to fit tightly around those parts. That is where the shrink ratio comes in.
