What are the effects of prolonged exposure to acidic rain on resin-based WPC outdoor tree boxes?

Prolonged exposure to acidic rain can significantly impact resin-based Wood-Plastic Composite (WPC) outdoor tree boxes. Acidic rain, with its low pH levels, may cause surface degradation, leading to discoloration, fading, and loss of aesthetic appeal. Over time, the acidic components can weaken the resin matrix, reducing the material's structural integrity and durability. This may result in cracks, warping, or brittleness, compromising the box's functionality. Additionally, prolonged exposure can accelerate wear and tear, shortening the product's lifespan. To mitigate these effects, consider using protective coatings or selecting WPC formulations with enhanced acid resistance. Regular maintenance, such as cleaning and inspections, can also help preserve the tree boxes in acidic environments.
