What are the effects of high humidity on polyethylene bench structural integrity?
High humidity can significantly affect the structural integrity of polyethylene benches, commonly used in outdoor settings. Prolonged exposure to moist environments leads to moisture absorption, which may cause plastic degradation over time. This results in reduced tensile strength, increased brittleness, and potential surface cracking. While polyethylene is generally water-resistant, constant humidity accelerates polymer chain breakdown, particularly in lower-quality variants. UV exposure combined with humidity worsens these effects. Proper maintenance and choosing high-density polyethylene (HDPE) benches can mitigate these issues, ensuring longer lifespan for outdoor furniture in humid climates.
