Insulation Tubing

Fiberglass tubing, bare and with silicone, PUR, and acrylic coating: the right choice of insulation

Fiberglass tubing with various coatings are indispensable component in the electrical industry when it comes to the safety and reliability of electrical systems. These highly specialized products provide first-class electrical insulation while withstanding the challenges posed by environmental influences such as extreme temperatures, chemical substances, and mechanical stress.

Silicone coating: flexibility and temperature resistance

Fiberglass tubing with silicone coating is known for its exceptional flexibility and temperature resistance. Together, these properties make them ideal for applications where components are exposed to high temperatures or where high flexibility is required. Commonly used in motors, transformers, generators, and other electrical equipment that must withstand mechanical stress and high temperatures. Depending on their thermal resistance, the tubing is divided into the following insulation classes.

Silicone-coated fiberglass tubing also offers excellent chemical resistance, making it suitable for use in environments where it is exposed to aggressive chemicals. Their flexibility allows for easy installation, even in complex applications.

Acrylic coating: chemical resistance and UV protection

In contrast, fiberglass tubing with an acrylic coating is characterized by its excellent chemical resistance and UV resistance. These tubes are particularly suitable for outdoor use or in environments where they are exposed to sunlight and aggressive chemical substances. The acrylic coating also offers good resistance to moisture, making it suitable for applications in humid environments.

Another advantage of the acrylic coating is its transparency, which makes it possible to check the condition of the underlying material without having to remove the tube. This is particularly useful in applications where visual inspection is important.

PUR-coated fiberglass tubing: Robust insulation for demanding environments

PUR-coated fiberglass tubing is characterized by robust insulation for applications that require high mechanical stress, chemical exposure, and environmental conditions. The key features of PUR-coated glass fiber sleeving include

• Robust mechanical strength: excellent resistance to mechanical stress and abrasion.
• Chemical resistance: Resistance to many chemical substances.
• Weather resistance: Protection against environmental influences such as moisture and UV radiation.
• Flexible adaptation: Robust but flexible and easy to handle.

Overall, PUR-coated glass-fiber sleeving offers a reliable insulation solution for demanding environments. Here, high demands are placed on mechanical strength, chemical resistance, and weather resistance.

Applications and choosing the right coating

Selecting between silicone and acrylic or PUR coating depends on the specific requirements of the application:

• Silicone coating is preferred in applications that require high temperatures, mechanical stress, and flexibility, such as motors, generators, and transformers.
• The acrylic coating is ideal for outdoor applications or in environments with aggressive chemicals and UV radiation. It is also used in areas where good visibility of the underlying material is required.
• PUR coating is particularly suitable for applications that require a combination of mechanical robustness and chemical resistance. It is often used in the automotive industry, in robotics applications, and in environments where the tubing is exposed to high mechanical stresses and must also withstand chemical substances.

Overall, coated fiberglass sleeving is an indispensable component for electrical insulation in a wide range of applications. By considering the specific requirements and environmental conditions, companies can choose the right coating to ensure the safety and reliability of their electrical systems.
