| Abstract: | The mechanism of thermal aging of silicone rubber was reviewed with 34 references. The influences of structure and composition of silicone rubber, such as the backbone, side group, end group, additives, and the environmental condition, such as water, acid, base, oxygen, ozone on the heat resistance of silicone rubber were analyzed. It was pointed out that changing the structure of backbone and side group, eliminating hydroxyl groups and adding heat resistant additives or a little silicone resin could improve the heat resistance of silicone rubber. |
