Low-temperature seal materials made of silicon rubber for space use

Silicon rubber features high temperature resistance,ultraviolet radiation resistance,and thermal/electrical insulation,which makes it an ideal sealing material in the space environment.However,the low-temperature-resistance property of silicon rubber is an issue that limits its applications in space.This paper reviews studies of low-temperature silicon rubber.Various properties of silicon rubber 6710 are discussed in view of their applications in space environment and related seal tests.The silicon rubber with low-temperature resistance is widely applied in the seal products of satellite,driving structures of airship,as well as space docking and life-protection system.But even lower temperature resistance is required in the field of space station and deep space probe,therefore more studies are expected for this kind of materials.
