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

When choosing materials for outdoor tables, resistance to mold is a critical factor, especially in humid or wet environments. PVC (polyvinyl chloride) and polypropylene are two popular options, each with distinct properties. PVC is highly resistant to mold due to its non-porous surface, which prevents moisture absorption and inhibits mold growth. This makes it an excellent choice for outdoor furniture exposed to rain or high humidity. On the other hand, polypropylene, while also resistant to mold, is slightly less effective than PVC because it can absorb minimal moisture over time, potentially leading to mold in extreme conditions. Both materials are durable and low-maintenance, but PVC's superior mold resistance gives it an edge for long-term outdoor use. Ultimately, the choice depends on your specific needs, but PVC is often the preferred material for environments prone to mold and moisture.
