EPDM rubber and NaOH
- Thread starter rob768
- Start date
I tried it for some strips to seal the top of a caustic washer operating at 140F. I made the choice based on the compatibility data in a handbook put out by Minor Rubber Co. What killed it was the small of mineral oil coming off the parts we were washing. If I could get rid of oil on the parts, I would still try EPDM.
According to my copy of Schweitzer's Corrosion Tables,
Nordel (EPDM) is resistant to concentrations of NaOH between 10% and 70% through to "concentrated" while enduring temperatures up to 300 deg. F.
As was swall's experience, it really depends what else is present in the liquor.
