Why is PVDF resistant to Stearic Acid?
PVDF shows excellent resistance to Stearic 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.
