PVDF temperature limit: 230°F (110°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Butyric Acid. 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.
