What are the effects of prolonged exposure to saltwater mist on PVC?
Prolonged exposure to saltwater mist can significantly impact PVC (Polyvinyl Chloride) materials, leading to various forms of degradation. Saltwater mist contains corrosive elements like chloride ions, which can accelerate the breakdown of PVC's polymer structure over time. Common effects include surface discoloration, loss of mechanical strength, and increased brittleness. In marine environments, PVC may also experience plasticizer leaching, reducing its flexibility and durability. While PVC is generally resistant to short-term saltwater exposure, long-term contact can compromise its performance, making it less suitable for harsh coastal applications without additional protective coatings or modifications. Regular maintenance and material selection are crucial for ensuring longevity in such conditions.
