How does the moisture absorption rate of polypropylene affect outdoor ottoman longevity?

Polypropylene is a popular material for outdoor ottomans due to its durability and resistance to environmental factors. However, its moisture absorption rate plays a critical role in determining its longevity. Polypropylene has a low moisture absorption rate, which means it resists water penetration and prevents mold, mildew, and structural weakening. This makes it ideal for outdoor use where exposure to rain and humidity is common.

Over time, prolonged exposure to moisture can still cause minor swelling or surface degradation, especially in low-quality polypropylene. To maximize longevity, choose high-density polypropylene with UV stabilizers to combat sun damage and ensure proper drainage to avoid water pooling. Regular cleaning and storage during extreme weather can further extend the life of your outdoor ottoman.

By understanding polypropylene's moisture resistance, you can make informed decisions when selecting and maintaining outdoor furniture for lasting performance.
