How does the porosity of polyethylene affect moisture retention in outdoor ottomans?

The porosity of polyethylene plays a critical role in determining how well outdoor ottomans retain moisture. Polyethylene, a common material for outdoor furniture, varies in density and pore structure, which directly influences its ability to repel or absorb water. High-density polyethylene (HDPE) has low porosity, making it highly resistant to moisture and ideal for humid or rainy climates. In contrast, low-density polyethylene (LDPE) is more porous, potentially trapping moisture and leading to mold or mildew growth over time.

For outdoor ottomans, selecting polyethylene with minimal porosity ensures better durability and longevity. Non-porous variants prevent water absorption, reducing the risk of damage and maintaining a dry seating surface. Additionally, treated or cross-linked polyethylene offers enhanced waterproofing, making it a superior choice for outdoor use.

To maximize moisture resistance, pair polyethylene ottomans with breathable covers or elevate them slightly to avoid prolonged contact with wet surfaces. Understanding polyethylene porosity helps consumers make informed decisions when purchasing outdoor furniture, ensuring both comfort and weather resistance.
