PVDF off ers optimum resistance to large part of organic and inorganic acids, to aliphatic and aromatic hydrocarbons, to alcohols and halogen solvents. Moreover it withstands Bromine, Chlorine and lodine type halogens, but not Fluorine.
All information are end results of dipping tests and, in some cases of direct tests.
Except di erent indications, mentioned solutions are all aqueous. The writing “SATURED” means that the solution is saturated at that concentration and at 25° C.
The indication “%” speci es the solute quantity in grams per 100 grams of solution.
