The stability and reliability of fluorosilicone oil in extreme aerospace environments are mainly due to its unique physical and chemical properties, which enable fluorosilicone oil to maintain stable performance under extreme conditions, thereby ensuring the normal operation of aerospace equipment. The following is a detailed analysis of the stability and reliability of fluorosilicone oil in extreme aerospace environments:


1. Stability in extreme environments
High and low temperature resistance:
Fluorosilicone oil has excellent high and low temperature resistance. Its main chain is composed of Si-O-Si bonds, which has a structure similar to that of inorganic polymers, with high bond energy, and the shielding protection of C-F bonds, so that fluorosilicone oil can maintain its physical properties at extremely high or low temperatures.
In the aerospace field, equipment often needs to operate under extreme temperature conditions, such as high-temperature engines, low-temperature space environments, etc. The high and low temperature resistance of fluorosilicone oil enables it to remain stable under these extreme conditions, and will not change performance or fail due to temperature changes.
Chemical stability:
Fluorosilicone oil has strong corrosion resistance and solubility resistance to a variety of chemicals, including acids, alkalis, solvents, etc.
In the field of aerospace, equipment often needs to contact various corrosive substances, such as fuel, oxidants, coolants, etc. The chemical stability of fluorosilicone oil enables it to maintain stable performance in these corrosive environments, and will not cause performance degradation or failure due to chemical reactions.
Low surface tension and waterproof and anti-fouling properties:
Fluorosilicone oil has a low surface tension, so it has good waterproof, anti-fouling and anti-sticking properties.
In the field of aerospace, equipment often needs to be exposed to harsh environments, such as rain, dust, oil, etc. The low surface tension and waterproof and anti-fouling properties of fluorosilicone oil can protect the surface of the equipment from pollution and erosion, ensuring the normal operation of the equipment.

2. Reliability in extreme environments
Excellent lubrication performance:
When fluorosilicone oil is used as a lubricant, it has a low friction coefficient and good lubrication performance. It can form a CF3 molecular assembly film with good hydrophobicity and oleophobicity on the surface of the friction pair, greatly reducing the friction factor of the friction pair and extending the service life of the equipment.
In the field of aerospace, the precision parts in the equipment need to operate under extreme conditions such as high speed, high temperature and high pressure for a long time. The excellent lubrication performance of fluorosilicone oil can reduce friction and wear between parts and improve the operating efficiency and reliability of the equipment.
Reliable sealing performance:
Fluorosilicone oil has good adhesion and elasticity, and can fit tightly to the surface of components to form a reliable sealing layer.
In the field of aerospace, the sealing performance of equipment is crucial. The reliable sealing performance of fluorosilicone oil can prevent the leakage of liquids, gases and solid particles, ensuring the normal operation and safety of equipment.
Electrical insulation performance:
Fluorosilicone oil has excellent electrical insulation performance and is suitable for the insulation and protection of electrical systems and electronic components in aerospace equipment.
In complex electrical environments such as high voltage and high frequency, fluorosilicone oil can maintain stable insulation performance to prevent electrical failures and safety accidents.

3. Comprehensive advantages and application prospects
The stability and reliability of fluorosilicone oil in extreme aerospace environments make it an indispensable lubricating and sealing material in aerospace equipment. With the continuous development of aerospace technology, the performance requirements for lubricants and sealants are getting higher and higher. Fluorosilicone oil has broad application prospects in the field of aerospace with its unique physical and chemical properties. In the future, with the continuous advancement of fluorosilicone oil preparation technology and the reduction of costs, its application in the field of aerospace will be more extensive and in-depth.


In summary, the stability and reliability of fluorosilicone oil in extreme aerospace environments have been fully verified and recognized. Its excellent physical and chemical properties enable fluorosilicone oil to maintain stable performance under extreme conditions, thereby ensuring the normal operation and safety of aerospace equipment.
