What role do stabilizers play in extending the lifespan of polyethylene outdoor sculptures?

Polyethylene outdoor sculptures are popular for their durability and versatility, but prolonged exposure to sunlight and environmental factors can cause degradation over time. Stabilizers play a crucial role in preserving these artworks by combating UV radiation, heat, and oxidative stress. UV stabilizers absorb harmful rays, preventing polymer breakdown, while antioxidants inhibit oxidation that weakens the material. Thermal stabilizers further enhance resistance to temperature fluctuations. Together, these additives significantly slow discoloration, cracking, and brittleness, ensuring sculptures remain vibrant and structurally sound for decades. Properly stabilized polyethylene can withstand harsh outdoor conditions, making it an ideal medium for public art installations and garden decor.
