When selecting urban outdoor leisure chairs, moisture and mildew resistance is crucial for longevity and maintenance. Among common materials, synthetic polymers like polypropylene and HDPE offer superior performance. These materials are inherently non-porous, preventing water absorption that leads to mold growth. Powder-coated aluminum provides excellent moisture resistance while being rust-proof, though joints may require sealing.
Teak wood naturally contains oils that resist moisture, but requires regular sealing maintenance. Recycled plastics perform well but may develop surface mildew without anti-microbial treatments. Vinyl straps drain quickly but can develop mildew underneath if debris accumulates.
For optimal performance in humid environments, polypropylene-based materials with UV stabilizers and aluminum frames with complete powder coating provide the best combination of moisture resistance, easy cleaning, and long-term durability against mildew formation in urban outdoor settings.
