How does the resistance to thermal cycling affect polyethylene outdoor armchair lifespan?
Polyethylene outdoor armchairs are popular for their durability and low maintenance, but their lifespan is significantly influenced by resistance to thermal cycling. Thermal cycling—repeated exposure to temperature fluctuations—causes expansion and contraction in the material, leading to stress cracks, warping, and eventual structural failure over time. High-quality polyethylene with UV stabilizers and additives improves thermal resistance, delaying degradation. To maximize lifespan, choose armchairs with thick, cross-linked polyethylene and avoid prolonged exposure to direct sunlight or extreme temperature shifts. Proper storage during harsh weather can also extend durability. Understanding these factors helps consumers invest in long-lasting outdoor furniture.
