The technological maturity of vinylidene fluoride (VDF) continues to improve, and polyvinylidene fluoride (PVDF) is its downstream product

Vinylidene fluoride (VDF), also known as 1,1-vinylidene fluoride, has a chemical formula of C2H2F2 and is an organic compound. Vinylidene fluoride appears as a colorless gas with a slight ether smell. It is soluble in ether and ethanol, and slightly soluble in water. Vinylidene fluoride is a fluorocarbon compound that has the characteristics of heat resistance, corrosion resistance, and good electrical insulation. It is widely used in the petrochemical industry.

After years of development, the maturity of vinylidene fluoride technology in my country has continued to improve, and output has continued to grow. The synthesis methods of vinylidene fluoride include vinylidene chloride method, cracking method, acetylene method and trifluoroethane HF removal method, etc. The cracking method refers to using R142b as the core raw material, adding high-purity nitrogen, and cracking it under high temperature and pressure to obtain cracked gas, which is then distilled, purified and other processes to obtain the finished product. This method is an emerging preparation method for vinylidene fluoride, which is simple to operate and The finished product has the advantages of good quality, high finished product yield, green and environmental protection, and is suitable for large-scale production.

According to the “2023-2028 China Vinylidene Fluoride (VDF) Industry Market In-depth Research and Development Prospects Forecast Report 》shows that the downstream product of vinylidene fluoride is polyvinylidene fluoride (PVDF). Polyvinylidene fluoride is a thermoplastic fluoropolymer with high temperature resistance, oxidation resistance, corrosion resistance, creep resistance and other properties. It is widely used in battery manufacturing, power systems, photovoltaics, petrochemicals, coatings and many other fields. Benefiting from the growth in application demand, my country’s polyvinylidene fluoride production capacity has expanded rapidly, and output has continued to grow, reaching 82,000 tons in 2022. In the future, as the development of the polyvinylidene fluoride industry accelerates, my country’s vinylidene fluoride market space will continue to expand.

Vinylidene fluoride also has broad application prospects in the field of fluorine rubber and can be used as a comonomer for fluorine rubber. There are many types of fluorine rubber, including fluorosilicone rubber, fluorine-containing fluorine rubber, and nitroso fluorine rubber, which are widely used in automobile manufacturing, home appliances, aerospace and other fields. In 2022, my country’s fluororubber market size will reach 120 million yuan. As market demand becomes increasingly strong, the development prospects of the vinylidene fluoride industry will continue to improve.

The main manufacturers of vinylidene fluoride in my country include Yonghe Co., Ltd., Sanmei Co., Ltd., Zhenfluoro New Materials, Juhua Co., Ltd., etc. Yonghe Co., Ltd. focuses on the R&D, production and sales of fluorine chemical products. Its main products include hexafluoropropylene oxide, polyvinylidene fluoride, hydrofluoric acid, etc. The company is currently actively promoting a vinylidene fluoride project with an annual output of 8,000 t/a. construction.

Industry analysts said that as a raw material for polyvinylidene fluoride, vinylidene fluoride has excellent comprehensive properties. In the future, as the development of downstream industries accelerates, Its market space will be further expanded. After years of development, the maturity of my country’s vinylidene fluoride technology has continued to improve, and the output and quality have further improved. In the future, with the continued efforts of local enterprises and increasingly strong market demand, the development prospects of my country’s vinylidene fluoride industry will continue to improve.
