What is fiberglass tape? What are its properties and applications?

Oct 25, 2025

In your daily life, you rarely see fiberglass tape. Even if you do see it, you might not recognize it. There's also a chance that the name might not match the actual product.

 

Fiber tape uses a fiberglass mesh yarn as its backing and a hot-melt pressure-sensitive adhesive as its bonding layer. It boasts extremely high tensile strength, is resistant to breakage, offers high-temperature resistance, provides thermal insulation, is electrically conductive, fire-retardant, corrosion-resistant, aging-resistant, weather-resistant, has a smooth appearance, offers strong adhesion, and is waterproof and abrasion-resistant. Therefore, it is widely used in a wide range of industries.

 

Fiber tape features:

1. The transparent PET backing is reinforced with longitudinal glass fibers, providing high tensile strength and resistance to friction, scratches, and moisture.

2. The specially formulated high-performance adhesive layer has a wide operating temperature range, allowing application in both winter (above 0°C) and summer conditions. (Note: The optimal operating temperature is between 15°C and 35°C. As the temperature decreases, the adhesive layer gradually hardens, making application more difficult.) Once applied, it maintains excellent adhesion over a wide temperature range.
3. Text or advertisements can also be printed on the transparent PET film to meet various needs.
4. The specially designed high-performance adhesive layer ensures optimal adhesion to most materials and leaves no residual adhesive or oil marks after removal.

 

In what industries is fiberglass tape commonly used?
First, it's used for securing large appliances. Residue-free tape has strong adhesion, tensile strength, and wear resistance, making it highly effective for sealing large appliances during transport and preventing them from opening. It's also reusable. Secondly, it's used for securing and connecting furniture and work tools. Its strength, unbreakable properties, and durability make it a strong and durable alternative to rope. Finally, it's used for wrapping heavy metal objects and steel. Due to the special properties of fiberglass tape, its strength and unbreakable properties make it a viable alternative to rope.

Also, it's used for common packaging and carton sealing. Fiberglass tape is, of course, an upgraded version of scotch tape, offering strong, durable packaging and auxiliary packaging. It has strong adhesion, resists debonding, and allows for long-term use. Furthermore, double-sided mesh fiberglass tape, due to its exceptional strength, is often used as door and window seals in the construction industry.
