| Abstract: |
| The crosslinking mechanism，preparation methods，crosslinking influencing factors，performance characterization and application prospects of silane crosslinked ethylene-propylene-diene rubber（EPDM） were introduced.The silane crosslinking of EPDM was divided into two stages：silane grafting and crosslinking.At present，the preparation techniques of silane crosslinked EPDM were mainly two-step method and one-step method.The formulation factors，grafting reaction temperature and time，and water bath crosslinking temperature and time had greater impact on the grafting reaction，hydrolysis and crosslinking reaction and properties of silane crosslinked EPDM. There were still many problems in the production process of silane crosslinked EPDM，and the application research of silane crosslinked EPDM should be further expanded. |
