What are Heat Shrink Wires

Also called a heat shrink tube, it is a tube that contracts when heated. When heat is applied to heat shrink tubing, the process inside the tube is activated, this allows the tube and the object it is superimposed on become a unified product.

What Do You Use Heat Shrink Wire for?

It’s used for isolation, strain relief, bundling or any function that needs a professional finish. It's a great way to protect electrical wires and cables from harmful elements such as water, oils, acids and other environmental hazards. The heat shrink is an alternative to the usual methods of isolation and can be used in a wide range of applications.

To protect your electrical equipment, wires and cables, you should also make use of waterproof connectors, it will also protect the wires against water, dust and other environment elements.

Polyolefin tube is a very popular option among heat shrink tubes on the market, because of its composition and technical properties. In general, polyolefin tubing is all purpose shrinkage product being available in many different styles for multiple uses.

In most cases, Thermo Tube is very easy to work with and simple to install. As it is available in a variety of sizes and colors, each one has a different application.

Depending on the tube, even a lighter can provide the necessary heat, but for total quality and safety, we recommend a thermal blower for application, which, in addition to being easy to use, concentrates heat evenly.

In addition to providing extra durability, heat resistance and other technical properties, the
heat shrink is also designed to give a perfect fit and not come off with time or use,
unlike electrical tape or other products on the market.

The maximum diameter of your cable bundle and the temperature range required by your
applications are important factors to consider when choosing heat shrink. As these products change size so drastically, the shrinkage rate of the thermotube it's also an important spec to consider so you get the right fit for your application.

Tube shrinkage ratio is the size of the original heat shrink in relation to its shape final shrunken, check it below:

2:1 – This tube will become half of its original size once the heat is
applied. The original heat shrink is twice as large as its shrunken form.
3:1 – This tube will be one-third of its original size once heat is applied. O
The original heat shrink is three times larger than its shrunken form.
4:1 – This tube will be a quarter of its original size once heat is applied. the term
original retractable is four times larger than its shrunken form
Use a compass, ruler, or even a string to measure the circumference of the object.
that you will be covering with the tube. After doing this divide by π to get the diameter. Pi (π)
equals approximately 3.14, but you must use your calculator to get a more accurate result.

For example, if the circumference of the circle is 10 cm, then the diameter is 10
cm/π, or 3.18 cm. Now just choose a thermotube with the closest final contraction. One
a good idea is to buy a slightly larger quantity because some tubes also shrink longitudinally.
