large percentage of polyurethane foam is produced in a nonApigmented or undyed form. The natural color of the foam immediately after production is white; however, the surface region of the foam begins to discolor and turns yellow over time due to chemical reactions initiated by UV light. This discoloration can cause problems with the perception of the quality of the foam although no actual property degradation has occurred. There are certain end-use applications (such as quilting, pillows, and…

Effect of catalyst residues on the degradation of rigid foam polyurethane
Immediately after heating rigid foam polyurethane (PU) at 165°C, it degrades in accordance with the degradation mechanisms suggested by Abu-Zeid et al. in earlier publications. However, after three
Photoacoustic study of UV, UV–thermal, and weathering degradation of rigid foam polyurethane
Degradation of polyurethane samples by UV, combination of UV–thermal, and natural weathering were studied by photoacoustic spectroscopy. This study reveals that degradation of polyurethane could be
