| Abstract: |
| The effect of addition level of curing agent DCP on the hot air aging property，hydrochloric acid and hydrogen sulfide corrosion resistance of tetrafluoroethylene-propylene rubber was investigated.The results showed that，the physical property of tetrafluoroethylene-propylene rubber increased after hot air aging，but decreased after hydrochloric acid and hydrogen sulfide corrosion.The corrosivity of hydrochloric acid，hydrogen sulfide and hot air descended successively.The better corrosion resistance of tetrafluoroethylene-propylene rubber in three mediums was attained when the addition level of curing agent DCP was 3 phr. |
