How does the resistance to chemicals of PVC compare to polypropylene in outdoor tables?

When selecting materials for outdoor tables, chemical resistance is a critical factor to consider. PVC (polyvinyl chloride) and polypropylene are two popular choices, each with distinct properties. PVC is known for its excellent resistance to a wide range of chemicals, including acids, alkalis, and oils, making it highly durable in harsh environments. On the other hand, polypropylene also offers strong chemical resistance, particularly against solvents and organic compounds, but may not perform as well as PVC in highly acidic or alkaline conditions. For outdoor tables exposed to cleaning agents, fertilizers, or other chemicals, PVC often emerges as the more robust option. However, polypropylene's lighter weight and flexibility can be advantageous in certain applications. Ultimately, the choice depends on the specific chemical exposure and environmental conditions the table will face. Both materials provide reliable performance, but PVC's superior chemical resistance makes it a preferred choice for demanding outdoor settings.
