How does prolonged exposure to rain affect the stability of PVC outdoor chairs?

Prolonged exposure to rain can significantly impact the stability and durability of PVC outdoor chairs. PVC (polyvinyl chloride) is a popular material for outdoor furniture due to its affordability and resistance to moisture. However, continuous rain exposure can lead to several issues. Over time, water absorption may weaken the structural integrity of the plastic, causing it to become brittle or warp. UV rays combined with moisture can accelerate degradation, leading to discoloration and reduced strength. Additionally, prolonged dampness may promote mold or mildew growth, further compromising the chair's lifespan. To maintain stability, it's advisable to store PVC chairs indoors during heavy rainfall or use protective covers to minimize water damage. Regular cleaning and drying can also help preserve their structural quality.
