is very simple if you grasp the following procedures properly.

  • The starting part is very simple. Choose the proper size of heat shrink tubing to prepare it a tight fit, be sure that the tubing diameter after shrinking is smaller than the diameter of the area you want to insulate. In this, you may need scissors to cut the tubing to insulate the wiring or the device.
  • Choose the heat shrink tubing according to its ratio so that it results in a tight fit. Since these products are available in a wide range of diameters. So select the one having the larger diameter that fits comfortably after shrinkage.
  • Slice the desired length of tubing and keeping in mind it also shrinks lengthwise. Measure it carefully, leaving for at least twenty-five percent for overlapping if there is connectors or insulation.
  • If you are joining cables or wires, then focus the tubing between the splice. Assuring that the tubing overlaps equally on both sides. Sometimes experts use grease or spray to splice the tubing easily.
  • Before utilizing heat, check the tubing specifications which recommended the heating temperature. High temperature or low temperature can lead to uneven shrinkage, insulation breakdown, or even physical damage. It is recommended to not to use the open flames. Any commercial heat shrink tubing gun or heat shrink oven can be used to shrink the tubing.

Heat Shrink Technology – Compositional Analysis

Different prescribed ranges of thermoplastics can be used for manufacturing a heat shrink tube. These include polyvinyl chloride, polyolefin, Neoprene, Kynar, Viton (generally used for purposes involving high temperature in corrosive environments) and fluorinated ethylene propylene.

Other adhesive lining tubes used for making cables and connectors are used for creating powerful seals that are water resistant in nature. For providing a conducting connection between different objects without soldering them, a conductive polymer thick film is added to the heat shrink tube.

Science Behind Heat Shrink Tube
In general, the majority of plastics don’t shrink when introduced to heat; however, a heat shrink tube does. The nature of a heat shrink tube can be attributed to its cross-linking process; then polymer, when subjected to a radiation, generates covalent bonds to facilitate the process.

It has been used heavily ever since the World War II and different analyses carried out in this regard have revealed that a plastic memory is induced to the covalent bond by the cross-linking of the polymer, thereby making sure that it can be stretched to the required shape. However, please note that the tube will restore its original shape on the application of the desired heat.


The extent of which a tube can shrink

Different heat shrink tubes have different shrink ratio – the shrink ratio is measured as the shrunken size of a tube to its original size. For example, a tube having 2:1 shrink ratio can have an expanded diameter that is twice the size of the tube in its shrunken state.

Applications of Heat Shrink Tube
Heat shrink tubing is used in numerous activities for both protection purposes as well as aesthetic enhancements.

Various other uses include:
Identification – Color coding is used for easy identification
To harness multiple wires
Longevity – For manufacturing long-lasting, durable labels which are used in networking patch cords
Sealing – For stopping water and dust from entering splices
Insulation – Against excessive heat in military vehicles, boats, and aircraft
Barrier – It serves as a barrier between cables and various corrosive materials
