This composition provides several advantages in terms of resistance to environmental and electrical stresses. Firstly, fiberglass has excellent thermal stability and does not degrade easily under UV radiation. The glass fibers are non-organic and do not absorb UV light, which means they do not break down or weaken when exposed to sunlight over time. This makes fiberglass fabric suitable for outdoor applications where UV exposure is a concern. Secondly, fiberglass is inherently non-conductive and has a high dielectric strength, which makes it resistant to electrical arcs. When exposed to an electrical arc, the fiberglass fabric does not conduct electricity, reducing the risk of electrical fires or damage. The material can withstand high temperatures generated by arc exposure without melting or burning, providing a protective barrier. Additionally, the structure of fiberglass fabric contributes to its durability. The interwoven fibers create a strong, flexible matrix that can absorb and dissipate energy from impacts or electrical discharges. This structural integrity helps maintain the fabric's performance under stress. While uncoated fiberglass fabric offers these protective qualities, it is important to note that coatings can enhance its performance further. Coatings can provide additional resistance to moisture, chemicals, and abrasion, extending the fabric's lifespan and effectiveness in harsh environments. In summary, uncoated fiberglass fabric resists UV and arc exposure due to its non-organic composition, thermal stability, non-conductive nature, and structural integrity, making it a reliable material for various industrial and outdoor applications.

Uncoated fiberglass fabric is inherently flame resistant. Fiberglass is made from fine fibers of glass, which is a non-combustible material. This means that it does not burn or support combustion. When exposed to high temperatures or direct flames, fiberglass fabric will not catch fire, and it will not contribute to the spread of flames. Instead, it may melt or degrade at extremely high temperatures, but it will not ignite. The flame resistance of uncoated fiberglass fabric makes it suitable for various applications where fire safety is a concern. It is commonly used in industries such as construction, automotive, and aerospace for insulation, fireproofing, and protective clothing. Additionally, fiberglass fabric is often used in the production of fire blankets and welding curtains, providing a barrier against sparks and flames. However, while uncoated fiberglass fabric is flame resistant, it is important to note that its performance can be affected by other factors such as the presence of coatings or treatments. Some coatings may enhance the fabric's properties, while others might reduce its flame resistance. Therefore, when selecting fiberglass fabric for specific applications, it is crucial to consider the entire composition and any additional treatments it may have undergone. In summary, uncoated fiberglass fabric is naturally flame resistant due to its glass composition, making it a reliable choice for applications requiring fire safety.
