| Sample | HDPE-GD-000 |
| Plastic Type | High-density Polyethylene (HDPE) |
| Molecular Formula | (C2H4)n |
| Color | Golden |
| Common use | Beverage bottle cap |
| Degradation details | Exposure to environmental conditions such as dust, dirt, temperature variations (without exposure to sun radiation) and to mechanical stress |
| Time of degradation | 2 years |
| Sample description | First, the sample was used as a beverage bottle cap and then it was degraded for 2 years in the conditions listed above. The sample has holes because it was also used for other applications. Below, you can see two Raman spectra of the sample with different backgrounds, depending on where we measured the spectra of the sample (inner or outer surface). |
