What environmental factors most significantly degrade WPC outdoor planters over time?
WPC (Wood-Plastic Composite) outdoor planters are popular for their durability and low maintenance, but they still face degradation over time due to environmental factors. The most significant contributors include prolonged UV exposure, which breaks down the polymer binders and fades the color. Moisture absorption can lead to swelling, warping, and mold growth, especially in humid climates. Temperature fluctuations cause expansion and contraction, weakening the material. Additionally, freeze-thaw cycles in colder regions can accelerate cracking. Regular cleaning and protective coatings can help extend their lifespan. Understanding these factors ensures better care and longevity for WPC planters.
