How do polypropylene sculptures handle prolonged exposure to acidic rainwater?
Polypropylene sculptures are known for their durability and resistance to harsh environmental conditions, including acidic rainwater. This synthetic polymer is inherently resistant to many chemicals, including weak acids commonly found in rainwater. Over time, prolonged exposure may cause slight surface degradation, such as dulling or minor discoloration, but the structural integrity of the sculpture remains largely unaffected. Unlike metals, polypropylene does not corrode or rust, making it a popular choice for outdoor art installations. Regular cleaning and occasional protective coatings can further extend its lifespan. Artists and conservators favor polypropylene for its balance of affordability, lightweight properties, and long-term resilience against weathering.
