How does the porosity of PVC affect mold growth in outdoor ottomans?
The porosity of PVC plays a critical role in mold growth on outdoor ottomans. Highly porous PVC absorbs moisture, creating a damp environment where mold thrives. Since outdoor furniture is exposed to rain and humidity, low-porosity PVC is preferable for resisting water retention and preventing mold. Manufacturers often use additives or coatings to reduce porosity, enhancing durability. Regular cleaning and proper storage also help minimize mold risks. Choosing high-quality, low-porosity PVC ensures long-lasting, mold-resistant outdoor ottomans.
