THE Paris Air Show will be a showcase for aerospace designers and reliability engineers in attendance to see DuPont’s full range of aerospace materials and solutions.
DuPont believes these parts can help improve performance and reliability, reduce weight and fuel consumption and support sustainability of aerospace systems.
Their Kalrez and Vespel parts aspire to provide innovative solutions to complex aerospace sealing, wear or friction challenges at high temperatures.
Kalrez perfluoroelastomer parts are used as oil seals in turbine and jet engines and air delivery systems.
Vespel parts offer high temperature capability, resistance to wear and low levels of friction. These parts replace metallic materials saving weight, improving fuel efficiency and contributing to operational cost reduction.
A further two products will be presented at the show, designed for sealing and wear: Tedlar polyvinyl fluoride films and Krytox lubricants.
Tedlar polyvinyl fluoride films attempt to give airlines maximum design flexibility in creating passenger.
The films have been qualified and used extensively in thermal/acoustic insulation blankets; they are used as fire barriers laminated to metals, labels for wiring, wire harnesses, and composite part labels where it is no longer acceptable to mechanically fasten metal plate labels to parts.
While most commonly used in bondable applications, Tedlar films are reportedly excellent release films used in the manufacture of advanced composite structures. Recently expanded capacity for Tedlar continues to enable existing and new applications benefitting the aircraft industry.
Krytox lubricants provide as oils and greases lubrication in technical applications such as cockpit instrumentation and landing gears. In the passenger cabin they eliminate disturbing noises.
DuPont’s Nomex and Kevlar honeycomb composites and fibres have been successfully used by the aerospace industry for more than 30 years, mainly being found in several aircraft parts.
