How does polyethylene handle exposure to bird droppings?
Polyethylene, a widely used plastic material, exhibits strong resistance to bird droppings due to its non-reactive chemical properties. The polymer's hydrophobic nature prevents absorption, while its dense molecular structure resists corrosion from uric acid and other components in droppings. High-density polyethylene (HDPE) performs particularly well, maintaining structural integrity even with prolonged exposure. However, frequent cleaning is recommended to prevent surface buildup, which could attract microbes over time. For outdoor applications like signage or construction, polyethylene remains a durable choice against avian-related weathering.
