Glass fiber has the advantages of light weight, high strength, and high mechanical strength. It has a wide range of downstream applications, involving electronic appliances, new energy vehicles, wind power generation, 5G, transportation and other fields. The downstream market demand is broad. my country is a major producer of glass fiber in the world. In recent years, under the guidance of national policies, the upgrading of the glass fiber industry structure has accelerated, and the development of the industry has gradually upgraded to green, intelligent, international, high-end and differentiated directions.
From the perspective of market segments, glass fiber can be divided into E-glass fiber, medium-alkali glass fiber, high-alkali glass fiber and alkali-resistant glass fiber according to different components. Among them, E-glass fiber is the mainstream product in the market, and its production capacity accounts for About 95.4%; according to the diameter of the single filament, glass fiber is divided into three types: roving, spun yarn and electronic glass fiber yarn. Among them, the roving market accounts for a relatively high proportion, reaching more than 70%. The market share of high value-added products such as electronic fiberglass yarn and spun yarn has increased.
