How does the resistance to mold of PVC compare to polyethylene 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 polyethylene are two popular options, but how do they compare in terms of mold resistance?

PVC is inherently resistant to mold due to its non-porous surface, which prevents moisture absorption. This makes it an excellent choice for outdoor furniture, as it can withstand damp conditions without promoting mold growth. Additionally, PVC is easy to clean and maintain, further enhancing its durability in outdoor settings.

On the other hand, polyethylene, while also resistant to moisture, is slightly more porous than PVC. This can make it more susceptible to mold over time, particularly in areas with high humidity or frequent rainfall. However, high-density polyethylene (HDPE) is often treated to improve its resistance to mold and other environmental factors.

In summary, PVC generally offers superior mold resistance compared to polyethylene, making it a more reliable choice for outdoor tables in challenging climates. However, the specific type of polyethylene and its treatment can also influence its performance. When selecting materials, consider the environmental conditions and maintenance requirements to ensure long-lasting outdoor furniture.
