Fiberglass (referred to as glass fiber) refers to an inorganic non-metallic material made of pyrophyllite and kaolin as raw materials through high-temperature melting, drawing, drying, winding and reprocessing of raw yarn. Glass fiber is a new type of material with superior performance, and it is also a new material that our country encourages to develop. In recent years, with the continuous favorable national policies and the improvement of enterprise research and development capabilities, the scale of the fiber glass industry has gradually expanded.
