FPM reaction
« on: July 22, 2021, 12:45:15 AM »
Could someone inform me as to why Sodium Hydroxide in aqueous form is not compatible with FPM but is compatible with EPDM?

If you google these elastomers you can se that FPM containes fluorine and that probably makes it sensitive to
strong hydroxide solution.

FPM is the ISO designation, FKM is the ASTM designation. VitonĀ®, Dai-El and Technoflon are brands for FPM polymers. All of the designations stand for one single base material, which is fluoro rubber. This rubber is used in applications that need O-rings that are resistant to high temperatures and chemical attacks.

But is this fluororubber resistant to hydroxide?
