MALIC ACID & PVDF Compatibility

Malic acid is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. In its ionised form it is malate, an intermediate of the TCA cycle along with fumarate. It can also be formed from pyruvate as one of the anaplerotic reactions.

PVDF temperature limit: 250°F (120°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Malic Acid (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.
