What cold flow properties affect WPC outdoor bar stool performance?
The performance of WPC (Wood-Plastic Composite) outdoor bar stools is significantly influenced by cold flow properties, which determine how the material deforms under prolonged stress and temperature changes. Cold flow, or creep, can cause sagging or structural weakening over time, especially in outdoor environments with fluctuating temperatures. Key factors include the composition of the WPC material, its density, and the additives used to enhance stability. High-quality WPC stools with optimized cold flow resistance maintain their shape and durability, ensuring long-term usability even in harsh weather conditions. Understanding these properties helps in selecting stools that balance aesthetics, comfort, and resilience for outdoor settings.
