What are the effects of resin degradation on WPC armchair structural integrity?

Resin degradation in Wood-Plastic Composite (WPC) armchairs can significantly compromise their structural integrity over time. WPC materials rely on a blend of wood fibers and plastic resins for strength and durability. When the resin component degrades due to environmental factors like UV exposure, moisture, or temperature fluctuations, the bond between wood fibers and plastic weakens. This leads to reduced load-bearing capacity, increased brittleness, and potential cracking or warping. Over time, the armchair may lose its shape, stability, and overall functionality. Regular maintenance and UV-resistant coatings can help mitigate these effects, ensuring longer-lasting WPC furniture. Understanding these risks is crucial for both manufacturers and consumers to make informed decisions about material selection and care.
