Hi,

I am looking for compatible plastics (PFA, PTFE, ECTFE, PVDF, PEEK, TFM) with:

1. 25% Tetra Methyl Ammonium Hydoxide- TMAH aqueous solution at 90 deg C
2. 25% TMAH solution in methanol at 90 deg C
3. 25% TMAH squeous solution + small amount of Glycidol Ether (surfactant).

I appreciate any help I can get.

Regards,
