3 to 1 Adhesive Heat Shrink Tubing Protection

Man is able to come up with innovative ways to protect electrical wire and cables through the years. Aside from the usual plastic coating or flexible sheaths, technology has provided for the development of tubing that is not only reliable and durable, but waterproof as well. It is a well known fact that moisture (or in general, water) has adverse effects on wires and electronic cables. Water can bring about corrosion and unnecessary disintegration of the conductor which may lead to greater losses, be it in residential, commercial, or industrial applications. Hence, the need for a reliable protector created a demanded for more creativity and innovation on the part of developers of wire and cable.  

Take 3 to 1 Adhesive Shrinkable Tubing as an example. It is developed around the idea of having two distinct parts, namely: the inner wall and the outer wall. It is important to note that the materials of construction used for each wall are two different components or materials. This is due to the fact that they are bound to play different roles in the shrinkable tubing. The outer wall is made of Polyolefin and is referred to as the heat shrink. On the other hand, the inner wall is commonly made of adhesive that melts down when subjected to heat. Since the tubing is made of two walls, it is usually referred to as dual wall tubing.

What happens to the 3 to 1 Adhesive Shrinkable Tubing when it is subjected to heat? Something good is bound to occur once the shrinkable tubing is subjected to temperature slightly lower than the known temperature of activation of the heat shrink. Once the optimal temperature is achieved, inner layer begins to take the gel form in such a way that it is like a stream of glue. After undergoing the process of heating and after everything cools down to the normal temperature, there exists a layer of adhesion between the shrinkable tubing and the wire. Not only that the resulting system is water proof, it is also assured that the wire or the component inside the shrinkable tubing will not experience any unnecessary movement that may be detrimental to the entire purpose of the electrical wiring.

The “3 to 1” in the nomenclature of the shrinkable tubing is rooted from the fact that it shrinks to 1/3 of the original diameter after subjecting it to the process of heating and cooling down. In addition, there is an estimated 15 percent average shrinkage rate if we look into the wire’s longitudinal aspect. In terms of standards, 3 to 1 Adhesive Shrinkable Tubing complies to the benchmark set by AMS-DTL-23053/4. The tubing can operate at temperatures between -55 degrees Celsius and 110 degrees Celsius. The shrink temperature is estimated to be at 90 degrees Celsius. The upper bound temperature, beyond which the tubing is expected to disintegrate is around 135 degrees Celsius.

Aside from insulation, this tubing can be used in wire identification, bundling of connectors, wire strain and stress relief, and insulation of solders.

Alpha FIT® Heat Shrink Tubing Products

Alpha FIT® Heat Shrink Tubing is incredibly popular nowadays thanks to its many advantages. Especially made for wirings, the product is easy enough to use for DIY projects and is incredibly versatile. For those who want to find out if this product is best for them, following are some of the advantages of this tubing type.

Very Durable

This type of tubing is incredibly durable whether it’s exposed to extreme heat or moist surfaces. This makes it perfect for basement wirings, ensuring that homeowners wouldn’t have to worry about the tubing deteriorating due to the wetness. What’s even better is that this product doesn’t decay overtime and comes with an extra layer of tubing to protect against unpredicted pressure. Compared to traditional tubing methods, the heat shrinking type can last considerably longer, providing a very cheap cost per year. The tubing is also capable of resisting mold growth and even corrosion.

Safe to Use

As previously mentioned, the Alpha FIT® Heat Shrink Tubing comes with an extra layer of protection, significantly boosting its safety level. Specially made for insulation purposes, the product has incredibly high resistance against electrical impulses. This is perhaps why tubing is perfect for DIY projects. The extra level of protection makes it possible for inexperienced electricians to plan their own wirings without too much of a risk.

Perfect Fit

The biggest attraction of heat shrink tubing is the fact that it allows easy fitting on various components. The capacity of the tube to shrink provides an excellent sealant, ensuring that the tubing will cover all the important parts while sliding over the large objects.

How to Choose One

There are various considerations people must take into account when buying heat shrink tubing. Aside from the obvious requirements like voltage ratings and temperature capabilities, the product must have the perfect fit.

When determining the size, buyers must look closely at the shrink ratio. This refers to how small the tubing will be once it is exposed to heat. For example, a 6:1 ratio means that the tubing is 6 times larger than it would be once it starts to shrink. The ratios range from 6:1 to 2:1, allowing users to find the best size that is needed for their project.

Of course, also take note of the voltage and heat requirements mentioned above. Buyers should first consider exactly where they intend to install the tubing and the environmental factors in that situation. This way, they will be able to pick the best type that would fit their needs.

Alpha FIT® Heat Shrink Tubing is mostly used for wire insulation, protection against conductors, for water-proofing, for wire repair, covering against wires and cables as well as an abrasion resistance. Note that although it is incredibly easy to use, working with electricity still poses risks to the individual. This is why when it comes to complicated wirings, it is advised that people use the service of an electrician and utilize the heat shrink tubing for long-term protection against any problems.
