Fiberglass is a high-performance inorganic non-metallic material with various types. Its advantages include excellent insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, it is brittle and has poor wear resistance. It is produced from six types of ores, including talc, quartz sand, limestone, dolomite, borax, and magnesite, through high-temperature melting, drawing, weaving, and other processes. The diameter of its single fiber ranges from a few micrometers to twenty or more, equivalent to 1/20 to 1/5 of a human hair. Each bundle of fiber yarn is composed of hundreds, even thousands, of single fibers. Fiberglass is commonly used as reinforcing material in composite materials, electrical insulation materials, thermal insulation materials, circuit boards, and various fields of the national economy.

Glass fiber products are widely used in various fields of the national economy, with electronics, transportation, and construction being the major three application areas. These also represent the development trend of the global glass fiber industry in the coming years.
