Heat shrink refers to a plastic tube with wondrous properties. This tube is utilized for abrasion resistance, insulating wires and protecting solid wire conductors, connectors and associated instruments from environmental impacts.  The manufacturing processes involved in the making of these tubes are often dependent upon its application. From the heavy wall tubing till the micro-sized thin walls, every type has a distinct design and feature in order to meet the demands.

These tubes are rated in accordance to their expansion ratio, where the more is the ratio the better will be the quality of heat shrink tubes.

How to Use Heat Shrink Tubes?

As mentioned before, these tubes are utilized primarily for preventative maintenance. For instance, when these tubes are fixed to connectors or terminals, then it can overcome physical stress which is often caused due to bending and flexing. Here, flexing & bending tend to wither cable’s conductor layer insulation, where just a layer of high quality shrinkable tubing allows the cable to withstand the damage even for those cable joints that have built-in strain absorber.

This is the reason why for challenging bending and flexing applications, the use of shrinkable tubing is often recommended. In fact, not only do these tubes provide strain relief but at the same time they even come up with an additional layer of insulation. It’s amazing electrical properties, makes it a valuable tool for terminations, circuit boards and connections too.

Role of Heat Shrink As a Cable Sealer

In case of cables, these tubes work as a protective cover by functioning as a sealer. They are placed over the connections, substrates, gaps or cable joints so as to protect them from chemical, dust and moisture. Moreover, the tubing even fights against environmental hazards by offering oxidation, corrosion, UV resistance too.

Though there are several preventative applications of the heat shrinks but they can even be used for repairing insulation or jacket, so as to ensure that the rest remains safe and secured.

How to Choose Appropriate Heat Shrinks?

There is a plethora of tubing available in the market, but the idea is to discover the one that stands appropriate according to your requirements. So, when you are confused about getting perfect tubing, there are a few factors that you can consider and they are

• Voltage ratings and Temperature
• Size requirements
• Thickness of wall and its rigidity
• How tubing behaves when heated

Making a note of these factors will help you in getting the ideal heat shrink boot that is looking for.

Other than identifying the best tubing for the purpose, it is equally important to go for a reputable company too. This is because only a professional company will help you in getting the products that you are looking for and that too at affordable prices. Therefore, first understand the type of tubing and its associated products boot, PVC caps and fittings that you need and then search for the best company around to receive value for money products.
