How do polypropylene sculptures perform in environments with high ozone levels?

Polypropylene sculptures are widely used in outdoor art due to their durability and cost-effectiveness. However, environments with high ozone levels can pose challenges. Ozone, a reactive gas, accelerates the degradation of many polymers, including polypropylene. Over time, prolonged exposure may cause surface cracking, discoloration, or brittleness.

To mitigate these effects, artists and manufacturers often add UV stabilizers and antioxidants to polypropylene. These additives enhance resistance to ozone and sunlight, extending the sculpture's lifespan. Regular maintenance, such as cleaning and protective coatings, can also help preserve the artwork.

While polypropylene isn't entirely immune to ozone damage, its performance in harsh conditions is superior to many other plastics. For long-term outdoor installations, selecting high-grade, stabilized polypropylene is crucial to ensure minimal degradation and lasting visual appeal.
