Fluorine rubber in daily life application field is very broad, such as auto parts, aviation and spaceflight, mechanical seals, pumps, reactor, mixer, the compressor shell, valve, all kinds of instruments and other devices used for valve seat, valve stem packing, diaphragm and gaskets, and in the rubber industry, semiconductor manufacturing industry, and the food and pharmaceutical industries are to play its role.
Such as unleaded gasoline and efi device used in the car, the fuel hose structure and material change is very big, the rubber has been used to replace nitrile rubber, fluorine rubber to reduce fuel penetration and further improve the heat resistance, rubber with composite structure, in which the fluorine rubber and chlorohydrin rubber or acrylic rubber, due to the fluorine rubber price is quite expensive, Therefore, the fluorine rubber layer is relatively thin, the thickness is about 0.2 ~ 0.7mm. This kind of structure fuel oil hose has become the mainstream product abroad. Our country has also developed this kind of fluorine rubber hose for the inner layer, and used in santana, Audi, Jetta, Fukang and other models of cars. In the high technical content of automobile engine, gearbox, valve oil seal, the main materials used are fluorine rubber, hydrogenated nitrile rubber and so on.
Fluororubber and silicone rubber composite oil seals have become the most commonly used engine crankshaft oil seals. Loading and unloading hydraulic system and large loading and unloading hydraulic system continuous working time is long, oil temperature and parts temperature rise quickly, ordinary rubber can not meet its work requirements, and fluorine rubber products with its excellent temperature performance, can meet all kinds of harsh technical requirements. With the continuous improvement of reliability and safety requirements in the automobile industry, the demand for fluorine rubber in the automobile industry also shows a rapid growth trend.
