How does saltwater exposure affect the structural integrity of polyethylene bar stools?
Polyethylene bar stools are popular for their durability and resistance to weathering, but prolonged exposure to saltwater can compromise their structural integrity. Saltwater accelerates the degradation process by causing oxidative stress, leading to surface cracks, brittleness, and reduced load-bearing capacity. Chloride ions in seawater penetrate the polymer matrix, weakening molecular bonds over time. UV radiation in coastal areas further exacerbates the damage. While polyethylene is inherently corrosion-resistant, frequent saltwater contact may shorten its lifespan. For marine applications, choosing high-density polyethylene (HDPE) or UV-stabilized variants can improve longevity. Regular rinsing with freshwater helps mitigate salt buildup and prolongs usability.
