How does polyethylene handle exposure to ocean spray?
Polyethylene, a widely used plastic, exhibits varying resistance to ocean spray depending on its density and formulation. High-density polyethylene (HDPE) generally performs better in marine environments due to its tightly packed molecular structure, which reduces water absorption and slows degradation. However, prolonged exposure to saltwater, UV radiation, and mechanical stress from waves can eventually cause surface cracking, brittleness, and loss of mechanical properties. Additives like UV stabilizers improve polyethylene's ocean spray resistance, but microplastic formation remains a concern. Studies show that while polyethylene doesn't corrode like metals, its long-term durability in ocean spray is limited by environmental factors and chemical breakdown processes.
