What are the differences in chemical compatibility between PVC and fertilizers?

PVC (polyvinyl chloride) is a widely used plastic material in various industries, including agriculture, due to its durability and cost-effectiveness. However, its chemical compatibility with fertilizers is a critical consideration for safe storage and handling.

Fertilizers often contain salts, acids, or other reactive compounds that can interact with PVC over time. While PVC generally resists many chemicals, prolonged exposure to certain fertilizers—especially those with high ammonium nitrate or urea concentrations—can cause degradation, leading to brittleness or cracks.

Additionally, liquid fertilizers with acidic or alkaline properties may accelerate PVC deterioration. For long-term storage, it’s essential to verify the specific fertilizer composition and consult PVC chemical resistance charts. Alternatives like polyethylene (PE) or coated metals may be preferable for highly reactive fertilizers.

Understanding these differences ensures safer material selection and extends the lifespan of agricultural infrastructure.
