Four methods to judge the quality of fiberglass cloth

Fiberglass cloth, made of woven fiberglass as the base material and coated with a polymer anti-emulsion, is widely used in wall reinforcement materials, reinforced cement products, and as a skeleton material for reinforced plastics and rubber products. Many people use fiberglass cloth, but how can you distinguish between good and bad quality?

**Method 1:** Judge the quality of fiberglass cloth by its appearance. High-quality fiberglass cloth has a clean surface, even and straight warp and weft threads, good durability, and uniform mesh size. Poor-quality fiberglass cloth has an uneven mesh and poor durability.

**Method 2:** High-quality fiberglass cloth has good chemical stability, is resistant to alkalis, acids, water, cement corrosion, and other chemical corrosion, making it safer to use.

**Method 3:** Judge the quality of fiberglass cloth by its color. High-quality fiberglass cloth has a glossy and uniform color, while poor-quality fiberglass cloth feels rough to the touch and has a dull, cloudy color.

**Method 4:** Method 4: Judge the quality of fiberglass cloth by stretching it. Good quality fiberglass cloth is not easily deformed and can recover its original shape after stretching, while poor quality fiberglass cloth will be difficult to restore its original shape after stretching, affecting normal use.
