How do resin-based outdoor sofas compare to WPC in terms of thermal expansion under fluctuating temperatures?

Resin-based outdoor sofas and WPC (Wood-Plastic Composite) furniture are popular choices for outdoor seating, but they behave differently under temperature fluctuations. Resin, being a synthetic polymer, generally exhibits lower thermal expansion compared to WPC. This means resin sofas are less likely to warp or crack in extreme heat or cold.

WPC, a blend of wood fibers and plastic, tends to expand and contract more with temperature changes due to its organic components. While WPC is durable, this expansion can lead to slight structural shifts over time. Resin, on the other hand, maintains greater dimensional stability, making it a reliable option for climates with significant temperature swings.

For long-term outdoor use, resin sofas often outperform WPC in resisting thermal stress, ensuring lasting comfort and aesthetics. Choose based on your local climate and maintenance preferences.
