The Material - chemical resistance

EFFECT OF VARIOUS HIGHLY CORROSIVE CHEMICALS

The outstanding chemical resistance of Ceramer and Ceramerplus to nearly all chemicals comes very close to that of Polytetrafluoroethylene (PTFE).
There is no known solvent even at very high temperatures which will dissolve Ceramer.
The chemical resistance is superior to that of PPS.
