Shrink tubing

Shrink tubing is flexible plastic tubing that shrinks when heated. They are often made of polyolefin, but can also be made of other materials such as PVC or fluoropolymers.

Heat-shrink tubing is used to insulate and protect electrical connections. When the heat shrink tubing is heated, it shrinks and fits snugly around the object it encases. This forms a waterproof and insulating layer around the connection. Heat-shrink tubing is used, for example, in the wiring of electrical appliances, in the automotive industry, in the installation of electrical cables and in the electronics industry.

In addition, heat-shrink tubing can also be used to bundle cables, to mark cables or to protect them from mechanical stress. They are available in different sizes and colors to meet individual requirements.

Heat-shrink tubing consists of a thermoplastic material that shrinks when heated. They are used to insulate and protect cables and other electrical connections.

The application of heat-shrink tubing is relatively simple. First, the heat-shrink tubing is slipped over the cable or connection to be insulated. The heat shrink tubing is then heated with a hot air gun or other heat source. During heating, the tubing shrinks and fits snugly around the cable or connection. This creates an insulating layer that protects against moisture, dirt and mechanical stress.

There are different types of heat shrink tubing with different shrink rates and shrink temperatures. It is important to select the right heat shrink tubing for the application in question to ensure optimum insulation and reliable protection.

If you are looking for heat shrink tubing that is versatile and comes in different colors and sizes, you have come to the right place. In our range you will find many transparent heat-shrink tubing and colored heat-shrink tubing that are suitable for different applications. You can buy heat shrink tubing from us for protecting cables, for insulation or simply for bundling wires.

Sometimes it's not just about insulation, but also about labeling cables. That's why we also offer colored heat-shrink tubing. These include, for example, green heat-shrink tubing and red heat-shrink tubing by the meter. With colored heat shrink tubing, you can not only protect your cables, but also clearly mark them to avoid confusion. A red heat-shrinkable sleeve is particularly effective.

Our shrink sleeves offer you the opportunity to customize your projects. We offer shrink tubing in different colors, such as red shrink tubing by the meter, blue shrink tubing by the meter or yellow shrink tubing. If you need something more discreet, we also offer black shrink tubing, brown shrink tubing or gray shrink tubing.

For special requirements, we also offer yellow-green shrink tubing, which is ideal for marking earth connections. You can also achieve discreet insulation with white heat-shrink tubing or clear heat-shrink tubing.

If you would like to see what is under the tubing, we recommend our transparent shrink tubing. Transparent shrink tubing is particularly practical if you need to carry out visual inspections. Whether transparent 30 mm heat shrink tubing, transparent 40 mm heat shrink tubing or transparent heat shrink tubing with adhesive. These variants offer you flexibility and security at the same time. The adhesive provides additional hold and protects your connections even better.

Do you need waterproof heat shrink tubing? We also have this on offer. These special tubes protect cable connections from moisture and are ideal for use outdoors or in damp environments. If you are looking for particularly robust protection, our thick-walled transparent heat shrink tubing is an ideal choice.

Our polyolefin heat-shrink tubing is the perfect solution for general insulation tasks. This material is very resistant and offers good shrink performance. Polyolefin heat shrink tubing is the best choice when you need high heat resistance and durability.

We offer shrink tubing in different types of packaging. You can order shrink tubing by the meter or shrink tubing in rolls if you want to be flexible in terms of length. For special projects, we also offer shrink tubing cut to size so that you get exactly the piece you need.

As a specialist in heat shrink tubing, we also have a heat shrink tubing Y in our heat shrink tubing store. This heat shrink tubing Y is a special heat shrink tubing that is used for branching cables. It has a Y shape, which makes it particularly suitable when a cable branches into two branches and you want to insulate all three connections (the main strand and the two branches) at the same time. The Y-shaped heat shrink tubing thus ensures a reliable, tight connection and protects the branch from mechanical stress, moisture and other environmental influences. This type of heat shrink tubing is often used in the automotive industry and in electrical engineering, where branches need to be protected safely and easily.

Whether you are looking for transparent heat-shrink tubing, white heat-shrink tubing or colored heat-shrink tubing, you can buy heat-shrink tubing from us in many variants, colors and sizes. Our colored heat shrink tubing is ideal if you want to mark cables or simply need a color match. With orange heat-shrink tubing, blue heat-shrink tubing or red heat-shrink tubing, you are not only focusing on functionality, but also on clear markings.

Shrinking heat shrink tubing correctly is not that difficult if you know what is important. With the right technique and the right tools, cables and connections can be safely insulated and protected. We have some information here on how to shrink heat shrink tubing correctly and which heat shrink tubing shrink temperature should be observed.

Before the heat shrink tubing can be shrunk properly, good preparation is crucial. First, the shrink tubing is cut to the right length. It should be slightly longer than the area that is to be insulated. This ensures that the ends of the cable are also well protected. The surface of the cable must be clean and dry. Dirt or moisture can prevent the heat shrink tubing from adhering properly.

The right shrink temperature is crucial for shrinking the heat shrink tubing correctly. The temperature of the heat shrink tubing depends on the material. Polyolefin shrink tubing, for example, requires a shrink temperature of between 90 and 120 degrees Celsius. However, there are also shrink sleeves that require higher temperatures, such as Teflon variants.
The best way to achieve the right temperature for the shrink tubing is to use a hot air dryer or hot air blower. This allows the temperature to be precisely controlled and prevents the tubing from overheating.

There are a few common mistakes that should not be made when shrinking heat shrink tubing. One of the most common mistakes is the wrong shrink temperature. If the heat shrink tubing is overheated, it can tear or melt. If the temperature is too low, it will not shrink completely and will sit loosely on the cable.
Uneven heat distribution also means that the tubing does not shrink properly. The hot air blower must therefore be moved evenly.
