| Why Plastics Fail (Part 2) |
| Very few plastics are totally impervious to all chemicals. Chemical failure occurring from exposing the products to certain chemicals is quite common. |
| Ultraviolet -
Zone of invisible radiation beyond the violet end of the spectrum of visible radiation. Since UV wavelengths are shorter than the visible, their photons have more energy, enough to initiate some chemical reactions and to degrade most plastics. |
