AMMONIUM HYDROXIDE & Polypropylene Compatibility

Ammonium hydroxide is a colorless aqueous solution with a pungent aroma. Te concentration of ammonia ranges up to approximately 30%. Ammonia vapors (which arise from the solution) irritate the eyes.

PVDF temperature limit: 200°F (95°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Ammonium Hydroxide (Up to “concentrated”). 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.
