Materials used in the aerospace industry have to withstand often adverse operating conditions on a continuous basis. Low pressures, high and low temperatures, rapid changes of temperature and pressure, intense radiation – WACKER silicones can withstand all of these because their property profile is tailored to each application.
Outer space is a hostile environment – extremely low pressure, intensive ionizing radiation, extreme cold and massive temperature fluctuations – there can be no room for compromises. Such adverse operating conditions and, more especially, the needs of satellite engineering prompted WACKER to work closely with major aerospace companies on the development of a range of silicone products with extremely low outgassing rates. Naturally, they comply with European Space Agency (ESA) standards concerning material properties, processing and durability.
- Minimal outgassing rates and hence no delamination under outer-space conditions
- High radiation resistance
- Full retention of elasticity down to the glass transition temperature at below -100 °C
- Dissipation of thermomechanical stress by virtue of silicones’ characteristic flexibility
- Lamination of the solar assembly to the support structure for the solar array wing
- Antistatic bonding of satellite components that are particularly susceptible to electrostatic charging
- Outstanding permanent flexibility
- Specialty grades are thermally stable from -30 to +250 °C
- Exceptional resistance to fluids, the elements, and UV radiation
- Very good molding and surface reproduction
- Sealing profiles for aircraft windows
- Abradable coating in jet engines
- Bonded joints and seals in the sanitary, galley and cabin areas
- Tool and auxiliary material in the production of composites for ventilation systems and the cabin interior
