I am looking for a good PETE Bottle Chemical Resistance Chart.
I was reading some older posts here and read one about Ammonia being shipped in a PETE bottle and the bad results when the bottle failed. It would be
nice to have a good chart to reference online somewhere. I was given 30 small PETE bottles that I would like to use for something safe. I thought
Ferrous sulfate solution may be one thing that would be safe in it but could not find a chart listing it. I would be nice to know which things can
and cant be safely put in them.

You can actually google it General Chemical Resistance of PET - Products
Ammonia, being a small molecule, easily goes into PET and performs a usual amidation of esters, leading to some kinds of terephthlamide. However,
stuff like dillute H2SO4 does not hydrolyse the PET at room temperature, because it can't easily peneterate it.Deathunter88 - 2-1-2016 at 09:34
Here is a more general guide to plastic chemical resistance:
Thank you very much for this link. I wanted to do this myself but just haven't gotten around to it. My wife drinks Diet Mountain Dew in 12 oz. PETE
bottles, and I can have all that I want. Mainly my interest is using them for ca. 1M aqueous solutions of various inorganic salts.

Thanks for this great chart. Do you have a reference for the source of it? (Happy New Year)-CharlieScopeGuy2 - 2-1-2016 at 23:34
The thanks for the chart. I am thinking that Ferrous sulfate is a week acid so it should not be put into PET bottles. My wife gave me a few HDPE
bottles that should work finesolo - 2-1-2016 at 23:52
