What are the effects of hydrocarbon exposure on PVC outdoor sculptures near roads?

PVC outdoor sculptures located near roads are frequently exposed to hydrocarbons from vehicle emissions, fuel spills, and industrial pollutants. Over time, this exposure can lead to significant material degradation. Hydrocarbons may cause discoloration, making the sculptures appear dull or stained. Additionally, prolonged contact can weaken the PVC structure, resulting in brittleness and cracks. The plasticizers in PVC, which provide flexibility, may also break down, accelerating wear. To mitigate these effects, protective coatings or regular cleaning is recommended. Understanding these impacts helps artists and conservators preserve public art in high-traffic areas.
