How does WPC outdoor ottoman thermal expansion compare to PVC?

When choosing materials for outdoor furniture like ottomans, understanding thermal expansion is crucial for durability. Wood-Plastic Composite (WPC) and Polyvinyl Chloride (PVC) are popular choices, but they behave differently under temperature changes.

WPC outdoor ottomans, made from a blend of wood fibers and plastic, exhibit moderate thermal expansion. The natural fibers absorb moisture, which can slightly amplify expansion in humid conditions. However, WPC's hybrid composition often provides better dimensional stability than pure plastic materials.

PVC ottomans, being 100% synthetic, expand more uniformly under heat but can warp or become brittle over time due to prolonged UV exposure. While PVC expands less than WPC in dry heat, it lacks the reinforcement of wood fibers, making it prone to cracking in extreme temperature swings.

For outdoor use, WPC generally offers better resistance to thermal stress, combining flexibility with structural integrity. PVC may require additional additives to match WPC's performance in fluctuating climates. Consider climate conditions and maintenance preferences when selecting between these materials.
