Aerospace

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.
