Why might polypropylene be preferred over PVC for outdoor ottomans in acidic environments?

When selecting materials for outdoor ottomans in acidic environments, polypropylene is often the superior choice over PVC due to its exceptional chemical resistance and durability. Polypropylene is inherently resistant to acids, alkalis, and other corrosive substances, making it ideal for harsh outdoor conditions where PVC might degrade over time. Additionally, polypropylene is highly UV-resistant, preventing discoloration and weakening from prolonged sun exposure. Unlike PVC, which can become brittle in extreme temperatures, polypropylene remains flexible and robust, ensuring long-lasting performance. Its lightweight yet sturdy nature also makes it easier to move and maintain. For outdoor furniture exposed to acidic conditions, polypropylene’s resilience and low maintenance requirements make it the preferred material.
