Fluorine rubber (FKM) refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms gives rubber excellent properties such as high temperature resistance, oxidation resistance, oil resistance, chemical corrosion resistance, and aging resistance. It also has good electrical and mechanical properties and is widely used in aerospace, missiles, and rockets. , ships, nuclear energy and other pointed end fields, as well as modern transportation, chemical industry, oil exploration, telecommunications, instrumentation, mechanical equipment and household appliances and other industrial fields, it is an irreplaceable key material in the national defense industry.
Fluorine rubber products are fluorine rubber 26 which is a binary copolymer of vinylidene fluoride (VDF) and hexafluoropropylene (HFP), and fluorine rubber 246 which is a ternary copolymer of vinylidene fluoride, tetrafluoroethylene (TFE) and hexafluoropropylene. Mainly fluorine rubber 23 copolymerized with ethylene and chlorotrifluoroethylene (CTFE), tetrapropylene rubber copolymerized with tetrafluoroethylene and propylene, fluorosilicone rubber, hydroxynitroso fluororubber, fluorinated phosphazene rubber, perfluoroether rubber Special fluororubbers have also been produced in small quantities. Fluorine rubber has the best comprehensive properties among all rubber elastomer materials.
According to the "China Fluorosilicone Industry Operation Briefing (Issue 129)", my country's fluorine rubber production capacity will reach 30,300 tons/year (including joint ventures), accounting for approximately 46.62% of the world's total fluorine rubber production capacity; within China (including foreign-funded enterprises) The total production capacity of fluorine rubber accounts for 56.15% of the total production capacity of fluorine rubber in the world. my country is the largest producer and consumer of fluorine rubber.
According to statistics, in 2022, the startup rate of my country's fluorine rubber devices will be about 86% (excluding joint ventures).
With the continuous development of China's economy, fluorine rubber, as a high-performance material, will be more widely used in various fields, and market demand will continue to increase.
In addition: According to public information reports, India's GFL is expanding its FKM production capacity from one production unit in fiscal 2022 to seven production units in fiscal 2023, bringing the total FKM production capacity to 7,000 tons/year.
