How does the addition of carbon black or other pigments influence WPC outdoor tree box performance?
The addition of carbon black or other pigments to Wood-Plastic Composite (WPC) outdoor tree boxes significantly enhances their performance and longevity. Carbon black, a common additive, improves UV resistance by absorbing harmful sunlight, preventing degradation and color fading. Pigments also contribute to better heat resistance, reducing warping or cracking in extreme temperatures. Additionally, these additives can improve the structural integrity of WPC, making it more resistant to moisture and microbial growth. By incorporating pigments, manufacturers can create visually appealing tree boxes while ensuring long-term durability in harsh outdoor environments. This makes WPC tree boxes a reliable choice for urban landscaping and commercial applications.
