Benefiting from the rapid development of the carbon fiber industry, the market size of carbon fiber sizing agents continues to expand.

Sizing agent is an important additive required in the production process of carbon fiber. It refers to a polymer substance that can form a film. Carbon fiber sizing agents have a wide range of functions. During the carbon fiber production process, sizing agents can bundle a large number of carbon fiber monofilaments into a bundle to prevent fiber fluffing and loosening. At the same time, after padding, adhesion, drying and other steps, sizing agents can also be used in A thin resin layer is evenly covered on the surface of the carbon fiber, which gives the carbon fiber a smooth, plump, and thick feel and improves the strength of the carbon fiber body.

According to different forms, carbon fiber sizing agents can be divided into solution type, emulsion type, and water-soluble sizing agents; according to different target objects, carbon fiber sizing agents can be divided into epoxy resin sizing agents, polyamide (PA) 66 sizing agents, and vinyl ester sizing agents. Resin sizing agent, polyethersulfone sizing agent, polyacrylonitrile sizing agent, etc.

According to the “Carbon Fiber Sizing Agent Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center, In recent years, as the trend of “replacing steel with plastic” continues to advance, the development speed of the carbon fiber market has continued to accelerate. In 2022, domestic carbon fiber production has reached 48,000 tons, a year-on-year increase of 79.1%. As a key additive required for carbon fiber production, the demand for carbon fiber sizing agents continues to increase, and the scale increases year by year. The domestic carbon fiber sizing agent market size in 2022 will be approximately 3.89 billion yuan, a year-on-year increase of 4.6%.

The development of the carbon fiber sizing agent industry is closely related to the development of the carbon fiber industry. In recent years, driven by the rapid development of the carbon fiber industry, the development potential of carbon fiber sizing agents has been continuously highlighted. As a result, domestic companies in the field of carbon fiber sizing agents are constantly increasing, mainly including Sinopec, Kangdexin Optoelectronic Materials, Jiangsu Hengshen Co., Ltd., Kingfa Technology, Rongcheng Carbon Fiber Technology, Weihai Extension Fiber, Zhongfu Shenying Carbon Fiber, and Guanghua Textile Group , Graphene Technology Research Institute, Feirongda Technology, Sanjiang Aerospace Jianghe Chemical, etc.

At present, in the context of the increasingly complex and diversified application environment of carbon fiber, carbon fiber sizing agent is a key material that affects the strength, feel, and performance of carbon fiber. Its market requirements are constantly upgrading, and it is expected to move toward high performance, multifunctionality, and specialization in the future. With continuous development, the industry has huge room for growth.

Industrial analysis personnel said that carbon fiber sizing agent is a key additive required for carbon fiber production. Currently, in domestic carbon fiber Driven by the rapid development of the industry, its market demand is increasing, and the industry shows good development prospects. At present, many companies in my country have entered the carbon fiber sizing agent market. In the future, as the market requirements for carbon fiber sizing agents continue to increase, local companies will need to continue to increase the research and development of innovative products and improve the level of production technology.
