Garden Grove, California – Saint-Gobain Seals will be exhibiting at the Paris Air Show in the Le Bourget Exhibition Centre June 15-21, 2015, and featuring their high temperature sealing and polymer solutions developed for demanding aerospace applications, in particular for critical parts in jet engine and APUs.
New solutions developed in jet engines to reduce fuel consumption and emissions lead to higher working temperature in the engine, which requires improved temperature capabilities for all components including seals and polymer solutions. New material formulations developed by Saint Gobain Seals help to reach these functional goals and provide precise polymer solutions that contribute to weight savings on the engine. Their OmniSeal spring-energized seals, OmniLip rotary shaft seals, and Meldin polymer components are designed to withstand extremely high temperatures (up to 350°C), and at the same time offer outstanding sealing capabilities and wear life and retain mechanical properties. Keeping track of current trends, Saint Gobain Seals’ R&D department has been focused on extending temperature capabilities for their seal and polyimide materials.
Applications on a jet engine include:
Meldin 7000 polyimide variable stator vane bushes in the LP and IP Compressor sections, which has excellent thermal oxidative stability and excellent retention of mechanical properties at high temperature. Together with wear resistance, this material is for a bushing application in a harsh environment with temperature above 300°C, high oxygen atmosphere, and high radial and axial loads.
OmniLip rotary shaft seals for the internal and accessory gearbox where high speed of the shaft is key with extremes up to 20,000rpm, in combination with temperature that can vary in a wide range (-50°C to 175°C).
OmniSeal spring-energized seals for the lubrication sump system, either in the compressor and turbine sections where high temperature (around 200°C), sealing capability at low pressure (lower than 2 bar), and chemical compatibility with jet oils are required.
Other Saint-Gobain business units will also be represented at the event: Sully, Aerospace, Specialty Films, Foams and Tapes, and Process Systems and will share Booth #E138 in Hall 2B with the Seals business unit.
