Silicone rubber materials have been widely applied in sealing
damping
cementing
and coating of spacecraft for their superior high-low temperature and radiation resistances
as well as excellent electrical performance. The environmental features of Low Earth Orbit (LEO) and the properties of silicone rubber materials in the resistances of vacuum
high-low temperature
atomic oxygen
and radiation were introduced
and the development trends of space-grade silicone rubbers were proposed.
