The low-temperature application of phenyl vinyl silicone in the field of aerospace is mainly reflected in its excellent low-temperature resistance and reliability in extreme environments. The following is a detailed analysis:

1. Low-temperature resistance of phenyl vinyl silicone
The impact of the introduction of phenyl: By introducing phenyl on the side group of polysiloxane, the crystallization temperature of phenyl vinyl silicone is greatly reduced, thereby significantly expanding its low-temperature application range. The presence of phenyl not only improves the cold resistance of silicone rubber, but also maintains its elastic properties at low temperatures.
Specific performance parameters: When the phenyl content is 5%~10%, phenyl vinyl silicone has unique cold resistance and can maintain the elasticity of rubber at low temperatures of -70℃ to -100℃. This performance is the best among all rubber materials.

2. Specific applications in the field of aerospace
Sealing rings and gaskets: Since aerospace vehicles encounter extreme temperature changes during flight, including extremely low temperature environments, sealing materials with high low-temperature resistance are required. Due to its excellent low-temperature resistance, phenyl vinyl silicone is often used as sealing rings and gaskets for aerospace devices to ensure the sealing and reliability of equipment in low-temperature environments.
Tubes and rods: In the aerospace field, some special parts need to withstand extremely low temperatures and maintain their structural integrity and functionality. Phenyl vinyl silicone is also used to manufacture tubes and rods for these parts due to its excellent low-temperature resistance.
Protection of electronic components: Electronic components in aerospace are extremely sensitive to temperature and need to be effectively protected. Phenyl vinyl silicone not only has low-temperature resistance, but also has good electrical insulation properties, so it is also widely used in the packaging and protection of electronic components.

3. Summary
The low-temperature application of phenyl vinyl silicone in the aerospace field benefits from its excellent low-temperature resistance and reliability in extreme environments. By introducing phenyl, the material significantly improves its cold resistance and can maintain the elastic properties of rubber at extremely low temperatures. In the aerospace field, phenyl vinyl silicone is widely used in the manufacture of parts such as seals, gaskets, tubes and rods, as well as for the protection of electronic components. These applications not only improve the performance and reliability of aerospace vehicles, but also promote technological progress and development in this field
