Most of the components of glass fiber are silicon dioxide, which is harmless to the human body, but it cannot be decomposed in the body, and it is easy to cause appendicitis and inflammation after eating.

However, it is an inorganic non-metallic material with excellent performance and a wide variety. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness.

Poor wear resistance. It is made from glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several microns to more than 20 meters.

Equivalent to 1/20-1/5 of a hair, each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fibers are commonly used as reinforcements in composites.

Electrical insulation materials, thermal insulation materials, circuit boards and other fields of the national economy.
