What causes old white plastic to turn yellow or brittle?
Old white plastic can turn yellow or brittle over time due to a combination of factors, including exposure to sunlight, heat, and chemicals. When plastic is exposed to UV light, it can cause the material to break down and react with oxygen, leading to the formation of chromophores, which are responsible for the yellowing effect. Additionally, plastic can absorb and react with chemicals in the air, such as pollutants and cleaning products, which can also contribute to discoloration and degradation.
In some cases, old white plastic may have been manufactured with impurities or additives that can cause it to degrade more quickly. For example, some plastics may contain UV stabilizers or antioxidants that can help prevent yellowing, but these additives can degrade over time, allowing the plastic to turn yellow. Understanding the causes of yellowing and brittleness is important for developing effective strategies for restoring old white plastic to its former glory.
