Chemical resistance of materials

Chemical resistance of materials

Chemical resistance of materials

(OP)
I am looking for a web site or referance that will list the chemical compatability of materials (metals, elastomers, plastics ...).  My current application is dealing with salt soluctions.  Some of the salts are ranging from: Magnesium perchlorates, Amomonium thiocyanate, Lithium chloride, Lithium iodide for ranges of 1-20%.  The solvents are ranging from Formic acid/Water chloride, acetone/water, Isopropyl/Isobutyl/ Methyl/ n-butly alcohols, Methylene chloride/ Dimethyl sulphoxide, Toluene, Acetone, Formamide, Benzene and a partridge in a pear tree.  I have looked on some manufacture web site, to find descrepancies for the same material or the solution is not listed.

Thank You for your assistance

RE: Chemical resistance of materials

Here is a good one from Nace.  It is a computer version of the Corrosion Data Survey.  Also there is the hard copy version.  If you are going to do a lot of materials selection the software or hard copy is a necessary asset.

If you would like to get a little deeper in to the science of material selection I would suggest you look at the  MEI courses at

RE: Chemical resistance of materials

My take on your requirements is you need a safe choice given all the various solvents, chlorides, ph considerations. Teflon should be considered strongly.

Becareful if using 'Teflon' there could be an issue with static discharge
