Fluorine and silicone rubber has good oil resistance, solvent resistance, resistance to chemicals and high and low temperature performance, is both escllent properties of silicone rubber and fluorine rubber elastomer, is currently the only can in medium - 68 ~ 230 ℃ lubricating oil and fuel oil used in the rubber material, can meet the organic silicon material organic fluorine material are difficult to meet even under the condition of extreme temperature sealing, coating, packing and impregnation The technical requirements of solvent resistance, oil resistance and acid and alkali resistance of materials.In addition, because the surface energy of fluorosilicone rubber is very low, it is also widely used as oil-resistant, solvent-resistant lubricants, isolators and defoaming agents.
Fluorine and silicone rubber is also used in the preparation of various types of locomotives, aviation spacecraft and chemical resistance to fuel and solvent on the oil seal, seal ring, oil seal and diaphragm tank, pipe, valve lining, rubber hose, the whole seal, o-ring, diaphragm and gaskets, and used in the electricity and electronics industry connection parts and cables, surface coating, such as conveyor belt, fabric is the defense industry, aerospace and oil Essential materials for industry.
At present, the global production and sales of fluorosilicone rubber (mainly hot-sulfide fluorosilicone rubber) have reached 3000 tons/year, mainly concentrated in the United States, Europe, Japan and other developed countries in the high-tech field, and automotive fluorosilicone materials and accounted for the main share.With the rapid development of China's economy, the amount of fluorosilicone rubber is also increasing, in 2004, the consumption of fluorosilicone material reached more than 200 tons.Our country fluorine silicon material mainly depends on import, there is no complete set of industrial equipment in China, the construction of this project can fill the domestic gap, change the situation of dependence on import, the market prospect is broad.
