| Abstract: |
| The properties of foam of chlorinated polyethylene rubber（CM）/waste EPDM powder blend were studied，the waste EPDM powder was modified by activator 420，and the influence of modification of waste EPDM powder on the foam properties was investigated.The results showed that，with the addition level of waste EPDM powder increasing，the Mooney viscosity of the blend increased，Shore C hardness decreased，the expansion ratio firstly increased and then decreased，and the foam shrinkage rate decreased.When the waste EPDM powder was modified，the Mooney viscosity of the blend changed very little，MH－ML value increased，physical properties and foaming shrinkage were improved，although the foaming ratio slightly decreased，and the cell structure was more compact and complete. |
