Methyl vinyl silicone rubber , methyl phenyl vinyl silicone rubber with a low content of-Ph2 SiO-, methyl phenyl vinyl silicone rubber with moderate content of -Ph2 SiO-, diphenyl ether ethyl-enesilicone rubber were made under the same processing and recipe and their properties , such as the ambient mechanical properties , thermo-oxidative stability at 300℃, damp heat aging at 70℃ and radiation resistance were investigated .Results show that the diphenyl ether ethylenesilicone rubber shows the best the mechanical properties and damp heat aging at 70℃ and radiation resistance but the worst thermo-oxidative stability at 300℃among the silicone rubber materials .The mechanical properties of methyl phenyl vinyl silicone rubber with a moderate content of -Ph2SiO-is worse, but show good thermo-oxidative stability at 300℃.Further-more, the damp heat aging of methyl phenyl vinyl silicone rubber with a low content of -Ph2 SiO- is the worst among the silicone rubbers .
