Can polypropylene withstand saltwater corrosion in coastal animal sculptures?

Polypropylene (PP) is a popular material for sculptures due to its lightweight, cost-effectiveness, and moldability. However, its resistance to saltwater corrosion in coastal animal sculptures is a critical consideration for artists and designers. Polypropylene is inherently resistant to many chemicals, including saltwater, making it suitable for marine environments. Unlike metals, it does not rust or corrode, though prolonged exposure to UV rays and extreme weather may cause gradual degradation. For long-lasting coastal sculptures, UV-stabilized or treated polypropylene is recommended. Proper maintenance, such as periodic cleaning and protective coatings, can further extend its lifespan. While not indestructible, polypropylene offers a durable and practical option for saltwater-exposed art installations.
