What role does surface reflectivity play in polyethylene’s interaction with sunlight?
Surface reflectivity plays a critical role in how polyethylene interacts with sunlight. As a widely used polymer, polyethylene is often exposed to UV radiation, which can lead to degradation over time. A highly reflective surface helps minimize sunlight absorption, reducing the risk of photochemical reactions that cause material breakdown. This property enhances polyethylene's durability in outdoor applications, such as packaging and construction. Additionally, additives or coatings can further improve reflectivity, offering better UV resistance and extending the material's lifespan. Understanding this interaction is key to optimizing polyethylene performance in sun-exposed environments.
