Plastic Chemical compatibility chart?
I found this chart http://www.coleparmer.com/techinfo/ChemComp.asp
but it does not include HDPE. Any other databases out there?

my partner downloaded some of these awhile back. One for protective gear like gloves is nice too since a chemist gets killed every once in awhile
from wearing the wrong kind of gloves

EXCELLENT!
Thanks, I see that HDPE and Oxidizers don't mix though. Bummer.
I bet those teflon containers are $s. :-)

And this encyclopedia includes glass: (briefly, HF, F2 (moist), AlF3, NH4HF2, Ca(OH)2, NaOH, KOH, Na2S to 50%, are incompatible with glass, hot phosphoric acid also attacks glass).

It would depend on the oxidiser, the storage conditions and the storage time. Remember always these charts are written for court to cover the
manufacturer, so they err on the side of caution, which is not a bad thing.
If you are not intending long term storage i would not hesitate using HDPE for oxidisers, i assume the warning is more due to incompatibility with one
of the myriad of processing additives used to make the hdpe blowable or melt-flowable or whatever.
I have a glass bottle of chlorine gas with a PP closure at STP, on my desk (to show people the colour). It has been there for about 4 years. The
colour in the closure has deteriorated but i have yet to have a whiff of chlorine.
If i haven't qualified myself enough, then just let me reiterate, it may be a disaster using HDPE instead of TFPE to store your oxidiser, but i highly
doubt it. If you use a simple PP (freezer bags) or PE(normal supermarket plastic bags) liner and just cable tie it closed within the HDPE container
you can sleep fairly easily. After all consider that the oxidisers commonly available at the hardware store use HDPE packaging throughout.
btw- thats an excellent compilation formatik especially the catpumps and flowline site
