What are the effects of hydrocarbon spills on the structural integrity of PVC?
Hydrocarbon spills can significantly compromise the structural integrity of PVC (polyvinyl chloride) materials. When exposed to hydrocarbons, PVC undergoes physical and chemical changes, including swelling, softening, and loss of mechanical strength. Over time, prolonged contact leads to cracking, brittleness, and eventual failure. The plasticizers in PVC are particularly vulnerable, leaching out and accelerating degradation. This makes PVC unsuitable for long-term use in environments with frequent hydrocarbon exposure, such as fuel storage or industrial settings. Preventive measures, such as protective coatings or alternative materials, are recommended to mitigate these effects.
