EXTRUDED PROPYLENE RESIN FOAM AND PROCESS FOR PRODUCTION THEREOF |
摘要 |
Extruded propylene-based resin foam according to the present invention is formed by extrusion-foaming a propylene-based resin, and the extruded propylene-based resin foam has a closed cell content of less than 40 % and an expansion ratio of 10 or more. Since the extruded propylene-based resin foam has an open-cell structure in which a cell-broken state is formed at a desired level and has a high expansion ratio, each cell in the foam has a sound absorption performance, such that the extruded foam is excellent in sound absorption performance. |
