LGF-PA66 corrosion resistance: seawater and high-chloride water?

PA66 (polyamide 66) offers excellent chemical stability, and the LGF-PA66 body has no electrochemica

PA66 (polyamide 66) offers excellent chemical stability, and the LGF-PA66 body has no electrochemical corrosion at all — the decisive edge over 304/316 stainless steel. Stainless bodies are prone to pitting in seawater, high-salinity groundwater and de-icing salt environments; the PA66 body is immune.

PA66 also resists dilute acids, dilute alkalis, salt solutions and oils, and is insoluble in common solvents at room temperature. Proven field cases include coastal seawater-intrusion monitoring wells, high-salinity wastewater metering in chemical parks, and road sprinkler systems exposed to de-icing salts in cold regions.

One limitation: PA66 has poor resistance to strong oxidising acids such as concentrated sulfuric and nitric acid. For those media, consult our technical team before selection and consider Hastelloy or titanium electrode options.
