| Abstract: |
| A flame-retardant foam sheet was made with self-developed EPR-modified PP.The sound adsorption of EPR-modified foam sheet was investigated by comparing to that of EPR-modified non-foam sheet.The results showed that the maximum sound adsorption factor of the foam sheet could reach above 0.98 at the medium and low frequencies ;and the average sound adsorption factor could reach above 0.52 at the frequencies from 125 to 2 000 Hz. |
