| Abstract: |
| The effects of the type and addition level of blowing agent as well as the addition level of aluminum powder on the sound absorption property of EPDM foam were experimentally investigated.The results showed that，when the addition level of blowing agent ACP W was 12 phr，the sound absorption property of EPDM foam in low and middle frequency was excellent because the curing rate matched the foaming rate.When the addition level of aluminum powder was 50 phr，the sound absorption property of the EPDM foam in low and middle frequency was obviously improved. |
