ABS plastic turns yellow due to UV-induced photo-oxidation of its butadiene component.
the verdict
SUPPORTED
the evidence backs this
confidence 81/100
Scientific literature confirms that exposure of ABS plastic to ultraviolet radiation induces photo-oxidation, leading to chemical degradation and discoloration.
