| 제목 | Aged properties of polyurethane foam via thermal and mechanical degradation |
| 초록 | Aging mechanism of polyurethane foam (PU) depends on thermal and mechanical degradation in aspects of its main applications. Existing researches have analyzed mechanical properties of aged PU foam or matrix in accordiance with the temperature, heating time, organinc liquid such as seawater, mechanical movements and vibrations. And there were some equations which correlate the levels of degradation factors with aged properties. In this work, aged properties of PU foam which are resulted from thermal and compressive(mechanical) degradation are throughly investegated via hysteresis loss, S65, S25, SAG factor, compression set, strut thickness density, swelling ratio, sol/gel fraction, and X-link density. |
