Gaskets and Seals Used in the Aerospace Industry

Gaskets and seals used in aerospace systems and equipment must be of superior quality and adhere to a high standard of production. Generally, they are found in an array of aerospace applications including radars, antennas, lighting, access panels, electrical conductivity, pressure sealing, and more. Because of their many uses, choosing the right aerospace gasket is essential. Apart from ensuring you select the correct gasket for your application, you must make sure it meets your criteria and performance parameters.

To begin, selecting a good rubber gasket should be based on the type of material it is made from. For commercial aerospace uses, the gasket material should have the capacity to withstand various levels of electrical resistance. More than that, you should consider acquiring a gasket that is corrosion-resistant and offers shielding effectiveness, fluid resistance, and exceptional performance under a wide range of temperature extremes. When such factors are a vital part of your operations, urethane-filled expanded aluminum gaskets are the perfect solution.
Urethane-filled expanded aluminum gaskets are impressive mechanical components that offer numerous benefits. They feature high surface affinity, and the association with urethane binder systems helps to create a sealing solution that fits perfectly within the fuselage and externally mounted aircraft devices. As such, you are guaranteed a seal with high chemical resistance to almost all aviation fluids.
In aviation applications, aerospace gaskets and seals must be able to withstand and survive lightning strikes. This is the reason that expanded aluminum is recommended, as it improves electrical performance and eliminates electrical contact resistance. Furthermore, expanded metal provides highly efficient electrical systems, enhanced grounding performance, and more. Urethane-filled aluminum gaskets in particular also help reduce corrosion, so aircraft manufacturers can expect less component replacement, saving them both time and money.
Over time, aluminum alloys have proven beneficial to airframes, given the associated stress fatigue and cracking they experience during flight. For such uses, urethane-filled expanded aluminum gaskets act as a conductive medium that promotes the even distribution of surface loads, thereby reducing and eliminating stress points and pitting occurrences. Furthermore, their corrosion-resistant characteristic results in a reduction in aircraft TCO, reducing water entry and the potential of creating an electrolytic environment.
