PETE Bottle Chemical Resistance Chart

ScopeGuy2 - 2-1-2016 at 00:54

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.

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.

Edit: Fixed quote formatting

Thanks for this great chart. Do you have a reference for the source of it? (Happy New Year)-Charlie

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 fine
