| Abstract: |
| The influence of the dynamic vulcanizing conditions and blending ratio on the tensile strength，hot oil resistance and compression stress relaxation of the fluoro rubber/EPDM blends was investigated.The results showed that the interference of two curing systems in the static vulcanization of fluoro rubber/EPDM blend was eliminated by using dynamic vulcanization；the tensile strength of the statically vulcanized blend was only about 2 MPa，while that of the dynamically vulcanized blend could reach over 10 MPa；the vulcanizing conditions had little influence on the physical properties of blends；and the hot air and hot oil aging properties of blends decreased as the EPDM proportion in the blends increased. |
