| Abstract: | The effect of manganese dioxide(MnO2) and tin dioxide(SnO2) on the heat aging resis-tance and thermal stability of RTV silicone rubber was investigated.The results showed that,the heat aging resistance of RTV silicone rubber was improved by using the proper addition level of MnO2 or SnO2.MnO2 could not improve the thermal stability of RTV silicone rubber significantly,which could be improved significantly when the addition level of SnO2 was more than 6 phr. |
