What happens if you put plastic under UV light?
Exposure to UV causes plastics to be attacked and deteriorate. When plastic absorbs ultraviolet light, the UV energy excites the polymers' chains, causing them to break. This causes the plastic to discolor, become brittle, and eventually crack. Elevated temperatures and oxygen tend to accelerate the deterioration.
