SODIUM NITRATE & PVDF Compatibility

Sodium Nitrate (NaNO3, CAS 7631-99-4) is a white, highly water-soluble salt and an oxidizer. It is used in fertilizers, explosives and pyrotechnics, glass and enamel manufacturing, molten salt heat transfer and solar thermal storage, metal treating, and as a food preservative. Sodium nitrate solutions should be kept away from combustible materials and reducing agents. 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 Sodium Nitrate (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.
