AMMONIUM CHLORIDE 25% & Polypropylene Compatibility

Ammonium Chloride 25% (NH4Cl, CAS 12125-02-9) solution is a clear, mildly acidic salt solution with a specific gravity of about 1.07. Ammonium chloride is used as a galvanizing and soldering flux, in metal finishing, dry-cell batteries, fertilizers, and as a clay stabilizer in oilfield fracturing and completion fluids. It is corrosive to many metals, so non-metallic storage tanks are commonly used. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.

PVDF temperature limit: 275°F (135°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Ammonium Chloride (Aqueous solution or solid). Arkema’s limits are for solid resin at atmospheric pressure and do not account for mixtures. Source: Arkema Kynar® PVDF chemical resistance chart. Confirm your application with Bailiff before ordering.
