| Sample | HDPE-WT-004 |
| Plastic Type | High-density Polyethylene (HDPE) |
| Molecular Formula | (C2H4)n |
| Color | White |
| Common use | Shower gel bottle |
| Degradation details | Exposure to indoor conditions – it was only used as a shower gel bottle for 3 months and then it was measured After indoor degradation, the sample was degraded in environmental conditions (for 3 months) such as wind, rain, snow, temperature variations and sun radiation. |
| Time of degradation | 3 months of indoor degradation + 3 months of environmental degradation |
| Sample description | The sample is rigid, clean with no visible signs of degradation after indoor degradation, but after environmental degradation, the sample was covered with dirt and water. Bellow you can find the Raman spectrum of the sample before and after the environmental degradation. |
