What are the thermal degradation thresholds for polypropylene outdoor seating?
Polypropylene (PP) is a popular material for outdoor seating due to its durability and resistance to moisture. However, understanding its thermal degradation thresholds is crucial for ensuring long-term performance. Polypropylene typically begins to degrade at temperatures around 120°C (248°F), with significant weakening occurring above 150°C (302°F). For outdoor seating, prolonged exposure to direct sunlight and high ambient temperatures can accelerate this process. Factors such as UV exposure, additives, and manufacturing quality also influence thermal stability. To maximize lifespan, choose UV-stabilized polypropylene and avoid placing seating near intense heat sources. Regular maintenance and shade can further extend durability.
