The materials used for these must have good thermal and mechanical properties as well as good resist- ance to aging. Cabin interior Because plastics are used in lighting systems, seats, the on-board kitchen and cooling sys- tems, in the oxygen supply, drinking water and disposal systems, as well as freight loading facilities, in some cases supplementary specifi- cations such as FDA, fungus test and drinking Material and parts water approvals are additionally required. Plastics used for such functions as fixing ele- ments, ball bearings, seals or sliding bearings Propulsion systems have excellent mechanical properties. For applications in machines, components or housings, materials are required above all to offer good thermal resistance and sliding properties. 4 TECAFORM AH natural (POM-C)TECAFORM AD natural (POM-H) TECAFORM 66) 66 natural (PA TECAMID natural PTFE (PTFE) TECAFLON GF40 natural (PPS) TECATRON PVX black (PEEK)TECAPEEK GF30 natural (PEEK)TECAPEEK natural (PEEK)TECAPEEK natural (PAI) TECATOR (PI) TECASINT � � � � � � � � � � Aerostructure Door fairings e Fuselage and tailplane components e Wings: e e e Slats and fl aps, boxes, panels Airframe: Doors, components, electrics, pipes and leads, e e e e e cable ducts Components Fasteners e e e e Bearings e e e Sealings e e e e e Bushings e e e Refuelling and fuel systems e e e e e e e e Equipment, system & support Actuation & Control Systems: Air management, thermal and power management, Aviation engine control, electrical landing system (ISR), sensors, e e e e e e e actuators and integration lighting, de-icing, fl ight control, door opening/closing control Landing Gear: Main and nose landing gear, steering system, extension/ e e e e e retraction system, kneeling system, wheels and brakes Cabin interior Seating, cabin lighting, galley, chilling systems, e e e e oxygen systems, drinking water systems, vacuum waste systems, cargo equipment Propulsion systems Engines and components: e e e e e e Propeller system, turbines Bearing bushes for engine guide vanes e Nacelles e e e Satellites Antenna covers (radomes), e e e e e e e bearing bushes, sliding elements (vacuum) Construction and insulation components Wire coils, sealing rings e e e Space Radar cover e Torque cylinder e e e Fixing elements e e e Pipe holders e e e e e e Key facts at a glance Due to their beneficial material properties, technical plastics offer wide-ranging application possibilities for the aerospace industry. 5 Product portfolio The basis for wide-ranging applications Over recent years, the significance of technical plastics has increased at an astounding speed.
