Chemical Resistance of PVDF

A = Excellent resistance only minor changes in weight, dimensions and properties, no irreversible damage caused by the medium (empirical values) 

B = Limited resistance distinct change in properties, at longer exposure irreversible damage (e.g., molecular degradation) possible, testing under application conditions required 

C = no resistance strong attack within short time period and/or stress crack formation, irreversible damage 

Carbon dioxide, carbonic acid, technical grade 120 A 

If not exposed to UV-light, PVDF is highly resistant against chlorine [861]

Much of the strength and chemical resistance of PVDF is maintained through an operating temperature range of —40 to +320°F ( — 40 to +160°C). 

Table A.36 Chemical resistance of PVDF diluted = aqueous solution, with iO%massin solution. Solution = aqueous solution, with >10% mass in solution, all%-values refer to water as the solvent [243] when no reference is given in the Comment column, the source is [243], in all other cases the reference is listed...
