Progress on Thermal Stability of Condensed RTV Silicone Rubber

The high temperature aging mechanism of condensed room temperature vulcanized( RTV) silicone rubber was summarized. Various modification methods,such as modifying the structure of main chain and side group,designing and developing a new type of vulcanized crosslinking system,adding new additives,among others for improving the thermal stability of the condensed RTV silicone rubber were reviewed. The paper also discussed the development trend for improving the thermal stability of condensed RTV silicone rubber.
