What are the temperature thresholds for polypropylene outdoor armchair usability?

Polypropylene outdoor armchairs are popular for their durability and weather resistance, but their usability depends on temperature thresholds. Typically, polypropylene remains stable between -20°C (-4°F) and 80°C (176°F). Below -20°C, the material may become brittle and prone to cracking, while prolonged exposure above 80°C can cause warping or deformation. For optimal longevity, avoid extreme temperatures and direct sunlight during peak heat. These chairs are ideal for moderate climates but may require protective covers or storage in harsh conditions. Understanding these thresholds ensures your outdoor furniture remains functional and attractive for years.
