The three above mentioned etchants normally have acid and pH will be
very low (< 1). Acrylic (PMMA) is ok for acid. I made a small
electrochemical test cell out of this stuff and have had 20% sulfuric
acid in it for weeks at a time and see zero effect to date.
Nylon is the common plastic you must avoid contact with acid for long
periods, even vinegar.
