| titleOfInvention |
Acoustical open-cell polyolefins and process for making |
| abstract |
This invention provides an expanded open-cell foam polymer composition comprising at least one linear or modified linear polyolefin, at least 50 % of the cells being open, and the cells having an average size of at least 1 millimeter. It is desirable that the composition have a sound absorption coefficient as determined by ASTM D 1050 at 1,000 Hz which is greater than 0.15. In preferred foams the composition has an airflow resistivity of less than about 800,000 Rayls/m. |
