What are the effects of prolonged shade on the durability of polyethylene outdoor chairs?

Polyethylene outdoor chairs are popular for their durability and resistance to harsh weather conditions. However, prolonged exposure to shade can have unexpected effects on their longevity. While shade protects against direct UV damage, it may also lead to moisture retention, promoting mold or mildew growth. Additionally, lack of sunlight can slow the evaporation of dew or rainwater, potentially weakening the material over time. Unlike UV-exposed chairs that may fade but retain structural integrity, shaded chairs might suffer from surface degradation due to prolonged dampness. To maximize durability, balance shade and sunlight exposure, and ensure proper ventilation. Regular cleaning and occasional sunlight exposure can help maintain the chair's strength and appearance. Choosing UV-stabilized polyethylene further enhances resistance to both shade-related and sun-induced wear.
