Fluorine rubber (FKM) has wide application fields and good industry development prospects.

Fluorine rubber (FKM) refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. Fluorine rubber contains fluorine atoms and has the advantages of oil resistance, oxidation resistance, corrosion resistance, heat resistance, etc. It is widely used in household appliances, aerospace, automobile manufacturing, defense industry and other fields. According to different chemical compositions, fluorine rubber can be divided into nitroso fluorine rubber, fluorine-containing olefinic fluorine rubber, fluorinated phosphazene rubber, fluorosilicone rubber, etc.

The main raw materials of fluorine rubber include vulcanizing agents, acid absorbers, raw rubber, reinforcing fillers, rubber accelerators, etc. Molding is a key link in fluororubber production and plays a decisive role in its quality and performance. At present, the mainstream molding methods of fluorine rubber include coating molding, flat plate molding, injection molding, extrusion molding, and injection molding. According to the “2023-2028 China Fluorine Rubber (FKM) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that different molding methods are suitable for different types of fluororubber. With the improvement of technological maturity, my country’s fluororubber production continues to grow, reaching 24,000 tons in 2022.

There are many types of fluororubber, including nitroso fluororubber, fluoroethylene fluororubber, fluorosilicone rubber, etc. Fluorosilicone rubber (FVMQ) has the properties of both organic fluorine and silicone and is widely used in many fields. Fluorosilicone rubber belongs to special fluorine rubber. my country is a major producer of fluorine rubber. However, compared with overseas developed countries, the technical level of my country’s special fluorine rubber is relatively backward, and high-end products must rely on imports. This is the main challenge facing the development of the industry.

Fluorine rubber is mainly used in household appliances, aerospace, automobile manufacturing, defense industry and other fields. In the aerospace field, fluorine rubber can be used to produce seals for high-temperature and corrosive chemicals such as lubricating oil, hydraulic oil, and fuel oil; in the automotive manufacturing field, fluorine rubber can be used to make engine oil seals, fuel hoses, and turbocharger soft rubber. Guan et al. Driven by downstream demand, my country’s fluorine rubber market continues to expand, reaching 120 million yuan in 2022.

There are many fluorine rubber manufacturers in my country, and the market competition is fierce. Haohua Chemical Technology Group Co., Ltd., Zhejiang Juhua Co., Ltd., Guoxin Culture Holdings Co., Ltd., Zhejiang Yonghe Refrigeration Co., Ltd., Shandong Dongyue Chemical Group, etc. are the main players in my country’s fluorine rubber market. In recent years, Juhua Co., Ltd. has focused on the technological transformation of fluorine rubber, and the company’s current annual production capacity reaches 3,000 tons.

Industry analysts said that fluorine rubber has a wide range of applications and the industry has good development prospects. my country is a major producer of fluorine rubber, and its output is growing steadily. However, currently, due to factors such as high technical barriers, my country is highly dependent on imports of high-end special fluororubber. It is expected that in the future, as the technical level of local enterprises continues to improve, my country’s fluorine rubber industry will gradually develop in a high-end direction.
