Are there oxidation inhibitors to prevent polyethylene degradation in polluted cities?
Polyethylene, a widely used polymer, is prone to degradation when exposed to pollutants, UV radiation, and oxidative stress in urban environments. To combat this, oxidation inhibitors such as antioxidants and UV stabilizers are added during manufacturing. These additives slow down the breakdown of polymer chains by neutralizing free radicals and absorbing harmful UV rays. Common inhibitors include hindered phenols, phosphites, and hindered amine light stabilizers (HALS). By incorporating these protective agents, polyethylene products—like packaging, pipes, and construction materials—maintain their structural integrity and performance even in highly polluted cities. Proper stabilization ensures longer service life and reduces environmental waste.
