How to Apply Heat Shrink Tubing

Heat shrink tubing is versatile, safe, affordable solution that is used to protect various electrical devices against scratch, chemicals, and weather conditions. It is also helpful for bundling the colored wires, terminations, and to provide insulation to the electrical devices with the help of heat shrink tubing gun.

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.

  • If you have to cover a cable of long length, which includes tubing, start shrinking from one end and slowly start working toward the other side. To guarantee that the tubing contracts smoothly and without air bubbles, rotate it while applying heat.
  • Confirms the shape of the cable, connector, hose, or tubing that it is covering. Quickly remove the heat source, and allow the tubing to cool gradually before applying physical stress on it.

Hope this blog helps you, how to use the heat shrink tubing and heat shrink tubing gun.



Get To Know More About Heat Shrink Tube Distributor

Heat shrink tubing is a quite engaging application and it serves a countless of purposes.
Although heat shrink tubing is the official title of the procedure, it is generally referred to as just heat shrink most usual.

Hence, to hire the heat shrink distributors is a worthy decision. There are a lot of benefits and features offered by the tube.

A Complete Guide Of Heat Shrink Tube:

Heat Shrink is a tube whose diameter is reduced when heat is applied to it. This pretty much makes the name of the application suitable when carrying out the procedure.

The purpose of heat shrink tubing is to also guard wires and small parts from damage. The combining and fixing wires also occurs when required. In a procedure like Electrical, Engineering heat shrivels tubing is utilized for associations, terminals, wires, and joints that should be cushioned.

Various Types Of Heat Shrink Tube:

Heat shrink tubing comes in various kinds and this is performed via the procedure of using a color code. This is performed so when we are dealing with connectors and wires the utilize of a color code makes things more attributable.

The procedure has received a note for being used rather generally when manufacturing personal computers. PCs take full benefit of heat shrink technology in order to have a complete better looking and more functional product.

Advantages Of Heat Shrink Tube:

Basically, heat shrink tubing is used because it can make multiple stiffnesses. Because of excessive thin walls, the product can add stiffness to a tool without remarkably joining to the width or size of the device. Because of this effect, varying degrees of flexibility can be obtained.

This tubing is used for electrical insulation because of its great dielectric and resistivity characteristics. It is maximum for including electrical components and insulating wiring to instruments. Moreover, manufacturers place this specific tubing over metal shafts for electrical insulation. The smooth tubing makes sure an error free transition over sharp edges and is defensive against fluid leakages.

Quick Start Guide to Heat Shrink Technology & Its Applications

Heat shrink tubing (also known as a heat shrink or) is a shrinkable plastic tube that is used for insulating wires, thereby providing environmental protection and abrasion resistance for stranded and solid wire conductors, terminals, connections and joints in electrical work.

The heat shrink kit, used around the world for multiple applications, was originally developed in the late 1950s by Paul Cook. It was manufactured using radiation chemistry. The heat shrink tube developed by Raychem is now used as the basic building block by different manufacturers worldwide.

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
