I have not found any direct information about the lubricating application of phenyl vinyl rubber in aerospace. But I can provide some basic knowledge about lubricating materials in aerospace and the types of materials that may be related to it.

In the aerospace field, the role of lubricating materials is crucial. They can not only reduce friction and wear between mechanical parts, but also maintain stable performance under extreme environments such as high temperature, high pressure, and high vacuum, ensuring the safe and reliable operation of spacecraft. Common aerospace lubricating materials include lubricating oil, grease, and solid lubricants.

Lubricating oil: In the aerospace field, synthetic oil is widely used due to its excellent performance. Synthetic oil has the advantages of good high temperature stability, strong low temperature fluidity, and strong oxidation resistance, which can meet the demanding requirements of lubricating oil in the aerospace field.
Lubricating grease: Grease is a semi-solid lubricating material with good adhesion and high temperature resistance. In the aerospace field, grease is mainly used for some parts that need to maintain lubrication for a long time, such as bearings, gears, etc.
Solid lubricant: Solid lubricant is a solid material that forms a lubricating film on the friction surface, which is mainly used for lubrication in some special environments, such as high temperature, high vacuum, strong radiation, etc. In the aerospace field, solid lubricants are mainly used to protect sensitive components such as solar panels and antennas from space dust and micrometeoroids.

Although phenyl vinyl rubber may have certain lubrication-related properties (such as wear resistance, high temperature resistance, etc.), it is not explicitly mentioned as a lubricant in lubrication applications in the aerospace field. However, with the development of materials science, phenyl vinyl rubber materials with better lubrication properties may be developed in the future and applied in the aerospace field.

In general, lubricating materials in the aerospace field need to meet extremely high performance requirements to ensure the safe and reliable operation of spacecraft. Therefore, when selecting lubricating materials, factors such as material performance, stability, adaptability and cost need to be considered comprehensively.
