The Case for Fiberglass: The 7 Advantages of a Versatile High-Heat Industrial Fabric

If you work in the heavy industry sector, you’re likely familiar with specialized thermal industrial fabrics. Finding heat-resistant materials that are durable, practical, and easy to work with can take some extra research and effort. But the heat containment professionals at Davlyn Group may have just the solution.

Enter fiberglass, a proven industrial material that can take many forms for various industrial applications. Fiberglass possesses chemical properties that are variable depending on its intended purpose. This versatile material can be used to make anything from a home’s roof, electrical cable insulation, and bathtub to supercars, aircraft, and boats. Several industries employ fiberglass because it is highly durable yet simultaneously lightweight.

Fiberglass can be made into fiber yarn, a commonly used industrial fabric favored for its functionality in the form of cloths, tapes, ropes, sleeving, and gaskets. Due to its chemical make-up, fiberglass is non-flammable, high-heat friendly, and maintains its shape even when exposed to extreme temperature changes. These are just a few qualities that make it an engineering favorite for heat containment functionality.1

Fiberglass insulation tape, fiberglass rope, fiberglass sleeving, and fiberglass gaskets are some of the best industrial fabrics for high-temperature use. Consider fiberglass for your next industrial project by reviewing seven of its most advantageous characteristics.

7 Advantages of Fiberglass as an Industrial Fabric

  • High-Temperature Resistance & Strength
  • Superior Electrical Insulation
  • Low Moisture Absorption
  • High Resistance to Industrial Chemicals
  • Exceptional Strength to Weight Ratio
  • Dimensional Stability
  • Flexibility with Other Materials


1. High-Temperature Resistance & Strength

Due to its composite, inorganic nature, fiberglass is non-flammable and can withstand high temperatures. It can tolerate some of the most extreme temps while still keeping its form. Fiberglass can retain 50% of its strength at 700° Fahrenheit and 25% at 1000° Fahrenheit, making it ideal for industrial use.2 Fiberglass is favored across several industries for its flexibility, which means it’s an easy material to manipulate into practically any shape or size. But despite its limber qualities, it is also incredibly durable, ranking more rigid than steel as a material offering the seamless intersection of form and function. Due to its durability, fiberglass has become commonly used in various applications.

2. Superior Electrical Insulation

With its flexible nature, fiberglass insulation tape is a practical option for sealing and insulating cylindrical materials. It is commonly used to protect hoses, electrical cables, or other items from heat. It works well for insulation, even when used in thin quantities. Tapes constructed from fiber yarns make it possible to seal and protect items from extreme temperatures. And because fiberglass is fireproof, it gives professionals great peace of mind when working with fire safety concerns. Its strength, flexibility, and low moisture absorption are also crucial traits that make it great for electrical work.

3. Low Moisture Absorption

Not only is fiberglass extremely resilient to heat elements, but it can be a good line of defense against moisture. The fiber yarn materials used to make fiberglass ropes and tapes are made of noncellular fiber materials, meaning they have very low moisture retention or absorption. This fiberglass feature can prevent mold and water exposure issues in many unique industrial applications.

Keep your equipment dry and safe. Check out Davlyn Group’s selection of fiberglass ropes and other low-absorption materials.

4. High Resistance to Industrial Chemicals

Since fiberglass is entirely artificial, it does not come with the same concerns as organic materials. Thanks to its low moisture absorption, you don’t have to worry about rotting, mildew, or deterioration. It will not react to chemicals or most acids, except hydrofluoric and hot phosphoric acid. These facts make fiberglass industrial materials incredibly practical and worth investing in, compared to other materials needing frequent replacement or those that quickly fall apart from chemical exposure.

Avoid hazardous chemical exposure for your personnel, equipment, and workspaces. Consider Davlyn Group’s fiberglass tapes, sleeves, and ropes to mitigate chemical exposure and decay.

5. Exceptional Strength to Weight Ratio

Fiberglass, despite being stronger than steel, is exceptionally lightweight. An example of one of its most ideal qualities, fiberglass’s light weight makes it easy to work with while remaining durable. Fiberglass industrial materials are twice as strong as steel wire. Another point for fiberglass textiles is that, unlike steel wire, it isn’t rigid and can be shaped according to your needs.

6. Dimensional Stability

Unlike organic materials, fiberglass will not shrink over time or warp when exposed to temperature fluctuations. Fiber yarns make industrial fiberglass tapes, and ropes won’t stretch or shrink due to atmospheric conditions. The nominal elongation at break is 3 to 4%, and the average linear thermal expansion coefficient of bulk E-glass is 5.4 x 10-6 cm/cm/°C.

7. Flexibility with Other Materials

You can adjust the chemical make-up of fiberglass depending on what you want to use it for. It comes in many forms and can be mixed with various materials, such as synthetic resin and cement. The same goes for fiberglass textiles; they can also be adjusted in strength, size, and make-up, depending on the desired end use.3

Fiberglass is not only structurally flexible but also offers flexibility in how and what it is used for. Davlyn Group has fiberglass industrial materials and textiles, including fiberglass cloths, tapes, ropes, sleeving, and gaskets, to facilitate high performance and ultimate protection for your personnel and equipment.
