The application demand for glass fiber sizing agents is growing, and reinforced textile sizing agents are expected to become mainstream products in the market.

Glass fiber sizing agent, also known as drawing sizing agent, is an aqueous solution or emulsion composed of a variety of organic and inorganic substances. It refers to the additives used in the processing of glass fiber. Glass fiber sizing can improve the surface state of glass fiber, meet the requirements of glass fiber drawing process, increase the lubricity of glass fiber, and plays an important role in the quality and performance of glass fiber.

Glass fiber sizing agents are mainly divided into three types: reinforced textile sizing agent, reinforced sizing agent and textile sizing agent. Reinforced textile sizing is a high-end glass fiber sizing agent that can be used in all aspects of glass fiber manufacturing and can be well combined with matrix materials. It is expected to become a mainstream product in the market in the future; enhanced sizing can improve the surface properties and aging resistance of glass fiber The textile sizing agent is a traditional glass fiber sizing agent and needs to be removed by post-processing after use.

The raw materials of glass fiber sizing agent include film-forming agents, softeners, lubricants, coupling agents, deionized water and pH adjusters, among which film-forming agents account for the main production cost. The film-forming agent used in glass fiber sizing agents is usually made of water-based polyurethane emulsion, bisphenol A epoxy resin emulsion, polyester emulsion, polyvinyl acetate emulsion, etc. Bisphenol A epoxy resin emulsion has the advantages of water resistance, anti-aging, corrosion resistance, heat resistance, etc. It can effectively improve the processability and wear resistance of glass fiber, and is suitable for the production of alkali-free glass fiber.

According to the “2023-2028 China Glass Fiber Sizing Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , the glass fiber field is the largest demand end for glass fiber sizing agents. my country’s fiberglass industry started early. After years of development, its technological maturity has continued to improve, leading to continued increases in output. my country is a major fiberglass producer and consumer, and local companies have a competitive advantage in the global market. Glass fiber yarn is a fiberglass end product. According to statistics from the China Fiberglass Industry Association, my country’s glass fiber yarn production will reach 6.87 million tons in 2022, a year-on-year increase of 10.2%. In this context, the demand for glass fiber sizing applications will continue to grow.

The main players in my country’s glass fiber sizing agent market include China Jushi, Jizhong New Materials, Zhengwei New Materials, Changhai Co., Ltd., Shandong Fiberglass, Sinoma Technology, etc. China Jushi is a representative enterprise of glass fiber sizing agent in my country, focusing on the research and development, production and sales of glass fiber products. Its glass fiber sizing agent production technology has reached the world’s leading level.

Industry analysts said that glass fiber sizing agents can improve the performance of glass fibers. As the development of downstream industries accelerates, its market demand is increasingly strong. . In recent years, Chinese companies have continued to increase research on the preparation methods of glass fiber sizing agents, leading to further improvements in product quality. It is expected that in the future, companies with high-performance glass fiber sizing agent production capabilities will occupy a larger space in my country’s market.
