What are the applications of FKM rubber in the aerospace field?
Fluororubber plays an important role in the aerospace field. Its excellent properties such as high temperature, oil, and chemical corrosion resistance make it one of the indispensable materials in aerospace engineering. The following are the detailed applications of fluoro rubber in the aerospace field:
1. Engine Seals
Fluororubber is widely used in seals in aircraft engines, such as turbine seals and piston ring seals. Under high temperatures, high pressure, and an oil environment, fluoro rubber can maintain excellent sealing performance to ensure the normal operation of the engine.
2. Fuel Tank Seals
The fuel tanks of aerospace vehicles require oil-resistant seals to prevent oil leakage. Fluororubber is widely used due to its excellent oil resistance. It can be used to seal fuel tank caps, doors, etc. to ensure safe storage and transportation of oil.
3. Hydraulic System Seals
The hydraulic system of aircraft requires high-performance seals to ensure the normal operation of the system, and fluoro rubber has become one of the preferred materials due to its high-temperature resistance, oil resistance, and pressure resistance. It can be used for sealing hydraulic cylinders, valves, pipes, and other components.
4. Avionics Equipment Seals
Avionics equipment usually requires seals to prevent moisture and dust from entering the equipment, and fluoro rubber is widely used in the sealing of electronic equipment due to its excellent chemical corrosion resistance and high-temperature resistance. For example, aircraft radar, communication equipment, navigation systems, etc. all require fluoro rubber seals.
5. Fuel System Seals
The aircraft fuel system requires high-performance seals to prevent fuel leakage. Fluororubber is often selected for its oil resistance and high-temperature resistance. It can be used for sealing fuel pumps, fuel tank connectors, nozzles, and other components.
6. Spacecraft Thermal Insulation Materials
In the design of spacecraft, it is necessary to consider the high-temperature environment that the spacecraft faces during the re-entry into the atmosphere. Fluororubber can be used as a component of thermal insulation materials to protect the internal structures and equipment of the spacecraft from high temperatures.
7. Thermally Conductive And Heat-Insulating Materials
In spacecraft, thermally conductive and heat-insulating materials are needed to manage the temperature inside the spacecraft to ensure the normal operation of the equipment. Fluororubber is selected for its excellent thermal conductivity and high-temperature resistance and is used to manufacture thermally conductive and heat-insulating pads, heat-insulating washers, and other parts.
8. Spacecraft High-Temperature Seals
When re-entering the atmosphere, spacecraft will face extremely high temperatures and pressures, and high-temperature seals are needed to protect the internal structure and equipment of the spacecraft from damage. Fluororubber is widely used in the manufacture of spacecraft seals due to its high-temperature resistance.
conclusions
FKM is widely used in the aerospace field, including engine seals, fuel tank seals, hydraulic system seals, electronic equipment seals, etc. Its excellent high-temperature resistance, oil resistance, chemical corrosion resistance, and other properties make it one of the indispensable and important materials in aerospace engineering.
