What are the effects of prolonged exposure to de-icing agents on WPC?
Prolonged exposure to de-icing agents can significantly impact the performance and durability of wood-plastic composites (WPC). Common de-icing chemicals, such as sodium chloride, calcium chloride, and magnesium chloride, may cause surface erosion, discoloration, and reduced mechanical strength in WPC materials. Over time, these agents can penetrate the composite matrix, leading to swelling, cracking, and accelerated aging. Additionally, repeated freeze-thaw cycles exacerbate the damage, compromising the structural integrity of WPC products like decking and fencing. To mitigate these effects, manufacturers often recommend protective coatings or alternative materials in high-exposure environments. Understanding these impacts helps in selecting the right WPC products for harsh winter conditions.
