It is entirely caused by the degradation of abs. This is usually due to an increased exposure to ultraviolet light, but it can also be due to excess heat, humidity, the cold, and other extreme.

Exposure to uv radiation can cause plastics to change color (turn yellow), crack, break, shatter or even melt! It just doesn’t cause the plastic to yellow. For one of the most commonly used plastics, polyethylene, it's long been suggested that ultraviolet (uv) light—the same light that gives us sunburns—initiates reactions. White plastic turns yellow over time due to a chemical reaction that occurs when it is exposed to light, oils,.
