Why is PVDF resistant to Chromic Acid?

PVDF shows excellent resistance to Chromic Acid due to its fluorinated polymer backbone providing excellent resistance to acids, bases, and organic solvents.

⚠️ When NOT to use PVDF

Avoid using Polyvinylidene Fluoride with strong bases (NaOH >10%), ketones, esters, and amines. Service temperature up to 150°C.
