Red heat shrink tubing
Our range includes heat shrink tubing in various colors, including red. Red heat shrink tubing is ideal when you want to mark it, for example, by writing on it.
Which types of red heat shrink tubing are there?
We offer five types of red heat shrink tubing:
- H-2(Z) – Thin-wall shrink tubing – 2:1
- H-2(3X) – Thin-wall shrink tubing – 3:1
- H-5(3X)-F – Thin-wall shrink tubing – 3:1
- HBTM – Medium-wall insulation shrink tubing for busbars – 2.5:1
- HBTH – Thick-wall insulation shrink tubing for busbars – 2.5:1
Each type is available in various sizes.
Why choose heat shrink tubing?
Heat shrink tubing is a simple and reliable solution to protect, repair, and/or mark cables and cable bundles. By cutting the heat shrink tubing to size, sliding it over the cable, and applying heat to shrink it, you can quickly and effectively install it. Heat shrink tubing provides protection in five ways:
- Mechanical protection – Protection against wear
- Electrical protection – Insulation of the cable
- Thermal protection – Flame retardant and self-extinguishing
- Chemical protection – Resistant to acids, salts, etc.
- Environmental protection – Protection against weather influences such as water and UV radiation
The level of protection depends on the type of heat shrink tubing, with the wall thickness playing an important role.
Advantages of thin-wall red heat shrink tubing
Three types of red heat shrink tubing in our range are thin-walled, with a wall thickness between 0.4 and 0.8 millimeters. This is the most commonly used type of shrink tubing and provides flexibility and bendability.
Thin-walled shrink tubing offers less abrasion protection than medium-walled or thick-walled shrink tubing, but is ideal for low-voltage applications.
How to use red heat shrink tubing
Follow these simple steps to correctly use red heat shrink tubing:
- Determine the correct diameter. Pay attention to the shrink ratio. For a diameter of 18 mm and a 2:1 ratio, it will shrink to 9 mm; with a 3:1 ratio, it will shrink to 6 mm. Always choose a post-shrink diameter that is slightly smaller than the cable diameter.
- Cut the heat shrink tubing to size. Make sure the length fits the part of the cable you want to protect.
- Slide the heat shrink tubing onto the cable. Place it in the desired position.
- Heat the tubing. Use a heat gun and move it evenly over the shrink tubing until it tightly fits around the cable.
Applications of red heat shrink tubing
Since cables are often dark in color, red heat shrink tubing is ideal for marking cables. The red color stands out well, making detection easy.
Additionally, red heat shrink tubing can be used to give dark cables a different appearance, for example, in areas where a more noticeable color is desired.
