UV radiation poses formidable challenges to materials like ABS because they lack good resistance to prolonged sunlight exposure. The most common and damaging of these effects is photodegradation, which manifests as chain scission, resulting in increased brittleness and a loss of mechanical properties. Research shows that in the absence of shielding, the impact strength of ABS could deteriorate by 20-50% over several months due to ultraviolet exposure of varying intensity and duration. Moreover, discoloration may occur wherein the material’s surface turns yellowish or chalky white as pigments and dyes undergo degradation.

To overcome these challenges, stabilizers and weatherable coatings are commonly integrated into ABS plastics to extend their outdoor application potential. Even so, these treatments do not fully resolve the problem. Protective measures, such as stronger outer layers, add to the costs of the primary material, while intense and prolonged sunlight may still cause some damage over the years. The need for frequent reapplication and replacement of materials in high-exposure areas greatly diminishes the product’s value. These constraints highlight the importance of foresight and planning when selecting materials for construction, where UV radiation is a critical design factor.
