How does polyethylene’s resistance to acids compare to other plastics?

Polyethylene is widely recognized for its excellent resistance to acids, making it a preferred material for containers and piping in chemical applications. Compared to other plastics like PVC, polypropylene, or nylon, polyethylene generally offers superior performance against a broad range of acids, including hydrochloric, sulfuric, and nitric acids at varying concentrations. While PVC also resists many acids, it can degrade under prolonged exposure to strong oxidizers, whereas polyethylene maintains stability. Polypropylene shares similar acid resistance but may not handle higher temperatures as effectively as high-density polyethylene (HDPE). Nylon, on the other hand, is less resistant to strong acids and bases. Overall, polyethylene stands out for its balance of affordability, durability, and chemical inertness, especially in industrial and laboratory settings.
