How do WPC outdoor tree boxes handle thermal cycling between day and night temperatures?

WPC (Wood-Plastic Composite) outdoor tree boxes are designed to endure thermal cycling caused by fluctuating day and night temperatures. The composite material combines wood fibers and plastic, offering superior thermal stability compared to traditional wood or plastic alone. During the day, WPC expands minimally under heat, while at night, it contracts without cracking or warping. This resilience is due to the plastic matrix, which absorbs stress and prevents structural damage. Additionally, UV-resistant additives protect against sun-induced degradation, ensuring long-term durability. Proper ventilation and drainage in WPC tree boxes further mitigate thermal stress, making them ideal for harsh outdoor conditions. Their low-maintenance, weatherproof nature makes them a reliable choice for urban landscaping.
