Chromic acid is aggressive, and inexpensive plastics won't hold up. But you can use PVDF, and it has been done. At least one company had a good sized booklet of applications on chrome plating solutions. Talk to Solvay (Solef®) or George Fischer (Sygef®) or one of the other manufacturers of PVDF.

Polypropylene filter cartridges will work on some chrome baths, but need to be checked frequently as they will eventually breakdown and cause the formation of trivalent as well as mess up the bath. did not have much problem with plain hard chrome, but an additive called Dura 60 would cause a breakdown in a day or two.

Fiberglass cartridges are available if you are not using a fluoride additive bath.

CPVC works fine for the canister and pipe.

Thanks Ted and Jim for the answer your gave me.

We have already bought this stuff. But I want to know what happens with the material substrate, I think it is positive using a filtration in a chrome solution. But I want to know more detail about the effects on the material.

Sincerely
