What are the effects of prolonged exposure to alkaline substances on WPC?
Prolonged exposure to alkaline substances can significantly impact the performance and longevity of wood-plastic composites (WPC). Alkaline environments may cause surface degradation, including discoloration, cracking, and loss of mechanical strength. Over time, the polymer matrix in WPC can weaken, leading to reduced structural integrity. Additionally, alkaline exposure may accelerate the breakdown of wood fibers within the composite, further compromising durability. To mitigate these effects, manufacturers often apply protective coatings or modify material formulations. Understanding these impacts helps in selecting the right WPC for environments with high alkaline exposure, such as industrial or coastal applications.
