ETHANOL & Polypropylene Compatibility

Ethanol (ethyl alcohol, C2H5OH, CAS 64-17-5) is a clear, colorless, flammable liquid with a specific gravity of about 0.789, a boiling point of 173°F (78°C) and a flash point of about 55°F (13°C). Ethanol is blended into gasoline (E10, E85), and is used as a solvent, in hand sanitizers and disinfectants, beverages, pharmaceuticals and extracts. Ethanol tanks need grounding, vapor venting and fire protection. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.

PVDF temperature limit: 230°F (110°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Ethyl Alcohol (Aqueous solution or liquid). 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.
