How does UV resistant plastic prevent degradation?
Posted: Fri Oct 17, 2025 8:48 pm
UV resistant plastic prevents degradation by incorporating special stabilizers and additives that absorb or reflect harmful ultraviolet (UV) radiation from sunlight. These compounds, such as UV absorbers and hindered amine light stabilizers (HALS), protect the polymer chains from breaking down over time. Without this protection, plastics can become brittle, discolored, and lose strength due to photodegradation. UV resistant plastic are widely used in outdoor applications such as automotive parts, construction materials, and packaging to ensure durability and long-term performance. By blocking UV rays, these materials extend the lifespan and maintain the integrity of plastic products.
