How does UV degradation affect the structural integrity of PVC outdoor armchairs?
UV degradation significantly impacts the structural integrity of PVC outdoor armchairs by breaking down the polymer chains in the plastic. Prolonged exposure to sunlight causes the material to become brittle, leading to cracks, discoloration, and reduced load-bearing capacity. Over time, this weakens the chair's framework, making it prone to breakage. UV stabilizers can slow this process, but without proper maintenance, PVC furniture will eventually lose its durability. Regular cleaning and protective coatings can help extend its lifespan. Understanding these effects ensures better care for outdoor furniture investments.
