Yes, polycarbonate can yellow with age and exposure to ultraviolet (UV) rays. This degradation occurs due to the breakdown of the polymer structure when exposed to UV radiation, leading to discoloration and loss of clarity. To mitigate this effect, many manufacturers add UV stabilizers to polycarbonate products, which can help prolong their lifespan and maintain transparency. However, even with these additives, some yellowing may still occur over time.
