What is the function of a heat shrink tube?

As its name suggests, a heat shrink tube shrinks when heated. An object will have its own characteristic shrinkage when its temperature reaches this stage. Heat shrink tubes are flame retardant, insulated, heat resistant and flexible. Such features determine their wide application. They are suitable for various harnesses, welding points, inductor insulation protection, and also can be used in various metal rods to prevent rust and corrosion.
