Key Role of Fluorosilicone Rubber in Aerospace Seals

Hits: 517 img

Fluorosilicone rubber, as a high-performance specialty material, has recently demonstrated irreplaceable value in the aerospace industry. Its excellent high and low-temperature resistance and chemical corrosion resistance make it the material of choice for seals in extreme environments.

Properties of Fluorosilicone Rubber:
Fluorosilicone rubber combines the advantages of fluororubber and silicone rubber, offering the following outstanding characteristics:

  • High and Low-Temperature Resistance: Maintains stable performance in extreme temperatures ranging from -60℃ to 250℃.

  • Oil and Solvent Resistance: Resists erosion from fuels, lubricants, and various chemical solvents.

  • Aging Resistance: Retains excellent physical properties even after long-term exposure to UV rays and ozone.

Applications:
In the aerospace industry, fluorosilicone rubber is widely used in the following scenarios:

  • Engine Seals: Used for high-temperature sealing in aircraft engines, ensuring stable operation under extreme conditions.

  • Fuel System Seals: Provides reliable sealing in fuel lines and tanks, preventing fuel leakage.

  • Spacecraft Protective Materials: Used in the outer protective layers of spacecraft to resist radiation and temperature fluctuations in space.

Industry Outlook:
With the continuous development of aerospace technology, the performance requirements for materials are becoming increasingly stringent. Fluorosilicone rubber, with its exceptional properties, will continue to play a critical role in this field, providing strong support for aerospace endeavors.
