Aerospace seals have high material requirements due to special working environment. For example, fuel tank seals need to consider whether the material can resist fuel corrosion, and its high temperature resistance, pressure resistance, vibration resistance, service life and other characteristics.

Seal is to prevent the internal material leakage of mechanical equipment, external impurities into the internal parts, in the industrial field is extremely widely used, with indispensable. The performance of seals directly affects the performance of mechanical equipment. Due to the special working environment in the aerospace field, the performance of seals is higher. Aerospace seals belong to high-end sealing products with high technical barriers.
