PHOSPHORIC ACID (<40%) & Polypropylene Compatibility

Phosphoric Acid is used for fertilizer and also in the food industry (oil, beverages, cheese, canned food, yeast, sugar, water) and other industries (pharmacy, detergents, animal feed, metal treatment, textile, pigments…)

PVDF temperature limit: 275°F (135°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Phosphoric Acid (Less than 85% in water). 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.
