PROPYL ALCOHOL & PVDF Compatibility

Propyl Alcohol (n-propanol, C3H7OH, CAS 71-23-8) is a clear, flammable alcohol with a specific gravity of about 0.80, a boiling point of 207°F (97°C) and a flash point near 59°F (15°C). Its isomer, isopropyl alcohol, is often called propyl alcohol in everyday use. Both are used as solvents for printing inks, coatings, cleaners and disinfectants, and as chemical intermediates. Propyl alcohol tanks need grounding and fire protection. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.

PVDF temperature limit: 150°F (65°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Propyl 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.
