| Abstract: |
| The effect of tin dioxide,barium sulfate,graphite and silica on the corrosion resistance of tetrafluoroethylene-propylene rubber was experimentally investigated.The results showed that,the hardness and tensile strength of tetrafluoroethylene-propylene rubber filled by different fillers were increased after thermal-oxidative aging.The physical properties were decreased significantly after HCl and H2S sour gas corrosion.It was found that the corrosion resistance against HCl solution and H2S sour gas could be improved by adding graphite,and the optimal addition level of graphite was 10 phr. |
