How do plastic outdoor chairs resist mold and mildew growth?

Plastic outdoor chairs are designed to resist mold and mildew growth through several key features. First, high-quality plastics like polypropylene or polyethylene are inherently moisture-resistant, preventing water absorption that fosters fungal growth. Many manufacturers also add antimicrobial additives during production to inhibit mold and mildew. The smooth, non-porous surface of plastic makes it difficult for spores to attach and thrive.

Proper design elements like drainage holes allow water to escape quickly, while UV-resistant treatments help maintain the material's integrity against weathering. Regular cleaning with mild soap and water further prevents organic buildup. Unlike natural materials, plastic won't rot or degrade from moisture exposure, making it an ideal choice for damp outdoor environments. For extra protection, some chairs feature textured surfaces that discourage moisture retention and improve airflow around the seating area.
