What are the differences in thermal expansion between WPC and resin-only flower boxes?
When comparing WPC (Wood Plastic Composite) and resin-only flower boxes, thermal expansion is a critical factor to consider for outdoor use. WPC, a blend of wood fibers and plastic, tends to expand and contract more significantly with temperature changes due to its organic components. Resin-only flower boxes, made from pure synthetic materials, exhibit lower thermal expansion, providing greater dimensional stability in varying climates.
WPC's higher thermal expansion can lead to warping or cracking over time, especially in extreme weather conditions. Resin boxes, on the other hand, maintain their shape better but may lack the natural aesthetic appeal of WPC. Understanding these differences helps in selecting the right material for long-lasting outdoor planters.
