Compatibility Rating
At 20°C (68°F)
Excellent
Excellent resistance - recommended for continuous use
At 50°C (122°F)
Poor
Not recommended - significant degradation expected
Why is PVDF resistant to Diethylamine?
PVDF shows excellent resistance to Diethylamine 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.
