| Rationale | Flowline's chemical compatibility chart rates Acetone 'Caution' for PVDF at every tested temperature - the one clear, singular exception to PVDF's otherwise near-universal Excellent rating across acids, caustics, oxidizers, salts, and most solvents captured in this project. Any quote that defaults to PVDF because 'it handles everything' must carry an explicit ketone/acetone exception, regardless of whether the PVDF component is a pump, valve, tank liner, or tubing. |
