Caustic Soda/Caustic Potash

These two mediums are also use in chemical processes for cleaning equipment from fouling.

These two mediums are aggressive against phenolic resin which tend to be corroded especially over 20% concentration @ 100°C. Low quality graphite face low lifetime in presence of caustic soda or caustic potash.

For applications requiring long lifetime, higher concentration and concentration GT developed grade GT KELITE+ with a much lower content of phenolic resin which allow resistance up to 50% @ 120°C.

For even higher conditions GT developed GT FLON and GT CARB+ grades which can withstand 80% concentration @ 250°C.

We can proceed to corrosion test or provide coupon for test on request here.

Our grade GT SIC is adopted for this media for higher temp & concentration.
