How does resin pigment loading affect mechanical properties of WPC flower boxes?
The mechanical properties of Wood-Plastic Composite (WPC) flower boxes are significantly influenced by the loading of resin pigments. Pigments are added to enhance aesthetic appeal, but their concentration can alter the material's structural integrity. Higher pigment loading may reduce tensile and flexural strength due to disrupted polymer matrix cohesion. Conversely, optimal pigment levels can maintain durability while achieving desired coloration. Factors like UV resistance and moisture absorption are also affected, impacting the longevity of WPC flower boxes in outdoor environments. Balancing pigment concentration with mechanical performance is crucial for producing durable, visually appealing products.
