The research progress of silicone rubber

Silicone rubber is a linear, high Mr (relative molecular mass) polysiloxane, its Mr generally more than 1.5×105, the molecular backbone consists of silicon atoms and oxygen atoms alternately (-Si-O-Si-), the bond energy of the Si-O bond (422 kJ/mol) is higher than the C-C bond (240 kJ / mol). Silicone rubber is non-toxic and tasteless, and
