With a good mechanical and chemical resistance, as well as a good resistance to climatic stress, elastomer seals are one of the key elements to ensure the operation and safety of an aircraft. To have these multiple features, manufacturers are working on a large variety of base materials including silicone, polyurethane or chloroprene. In addition to their solidity and durability, elastomer seals guarantee the sealing of the aircraft, whether in terms of engine and flight mechanisms, or in the cockpit and cabin.
