How are polyethylene sculptures protected from UV degradation without painting?

Polyethylene sculptures are often exposed to outdoor environments, making them susceptible to UV degradation. To protect these artworks without painting, several methods are employed. One common approach is the incorporation of UV stabilizers and antioxidants into the polyethylene material during manufacturing. These additives absorb or block harmful UV rays, preventing molecular breakdown. Another method involves using carbon black or other pigments that naturally deflect UV radiation. Additionally, some sculptures are coated with clear UV-resistant films or lacquers that provide protection while maintaining the original appearance. Advanced polymer blends with inherent UV resistance are also becoming popular. These techniques ensure the longevity of polyethylene sculptures while preserving their aesthetic integrity.
