Aircraft Sealant Applications
Take Off Into the Future
Aerospace is a trendsetter when it comes to innovation. Air traffic is becoming ever faster, safer and more efficient. The performance of the aircraft is increasing, at the same time the footprint of flying is to be reduced in the sense of sustainability. Airplanes therefore fly higher and higher in ever colder air layers; at the same time, their engines are operated at extremely high temperatures with environmentally friendly “lean” fuel mixtures. In addition, alternative fuels are gaining in importance on the road to sustainability towards carbon-free aviation, a long-term goal of the International Air Transport Association (IATA).
These trends are full of technical challenges and are tailor-made for a company that specializes in technology like Freudenberg Sealing Technologies. Whether with new materials, lightweight components, sophisticated designs or innovative technologies: with our global expertise in the aerospace industry, we have the right sealing solutions at hand. We thus give the entire industry a boost to take off into the future.
The quality, safety and reliability of our products are of particular importance in view of the extreme requirements that the aerospace industry places on seals. People’s lives depend on it. We have unique materials expertise, innovation, operational excellence and innovative simulation and testing capabilities to meet all industry specifications – whether with temperature- and media-resistant standard parts or tailor-made individual solutions. Around the globe, in all relevant markets.
Product Range for Aerospace
Freudenberg Back-up Rings for the Aerospace industry support the sealing capability of O-rings by supporting against extrusion. Our Back-up Rings expand the operations conditions of O-rings while maintaining the flexibility to be used with a variety of seals. These retainers are available as solid elements, scarf cut, or as spiral rings. Back-up Rings are ideally suited to increase product life in high-pressure and extreme-temperature applications.
Omegat OMS-CS Cap Seals
Consisting of an engineered PTFE ring and an O-Ring as energizer in a two-piece rod seal set, Freudenberg’s Omegat OMS-CS Cap Seal is specifically designed for use in dynamic, reciprocating Aerospace applications when low friction is required. The special design of the anti blow-by notches assists a typical pressure peak within the O-ring at the rounded edge of the PTFE profile ring. These angled anti blow-by notches avoid additional sharp edges at this mostly stressed area of the O-ring. That means maximum protection of the O-Ring preventing premature failure.
As a fire-resistant fire protection barrier, our sealing solutions withstand temperatures of 2,000 degrees Fahrenheit (1,093 degrees Celsius). This opens up a 15-minute window for fire-fighting and life-saving measures.
Freudenberg solutions not only reliably seal cabin doors, windows or hatches. With low-friction surfaces and lightweight materials, they also meet the goals of efficiency and sustainability.
Thanks to Freudenberg’s unique range of materials, our O-rings are true all-rounders on board. Their temperature and chemical resistance benefits engines, wheels, brakes, control systems and hydraulic actuators.
Easy to assemble, cost-effective and multifunctional: Our application-specific optimized flat gaskets withstand extreme temperatures in engines and are used in fuel systems.
Polytetrafluoroethylene (PTFE) is a low-friction special material that offers almost universal chemical resistance. PTFE seals for the aerospace industry are particularly durable and offer top performance in a wide temperature range.
Original Simmerrings from Freudenberg in metric and Anglo-American inch sizes are standard equipment on airplanes: in engines, transmissions, control systems, wheels and brakes.
Diaphragms developed and tested in-house for specific customers and applications are made of high-quality elastomer and polyurethane materials, tailor-made high- and/or low-temperature compounds and are available with fabric reinforcements.
The continuous quest for faster, safer, more efficient air travel demands ongoing innovation. The industry continues to strive for improved performance, reduced environmental impact, operational efficiency, and reductions in weight and cost.
