Nitrile Rubber for Caustic
Nitrile Rubber for Caustic
(OP)
I have a spray washer on a paint line which is sealed at the top with rubber strip material to allow the parts hangers to pass through. The caustic cleaner (spray) is 4% sodium hydroxide at 140F.How well will nitrile hold up under this environment? I tried EPDM, but the oil coming off the parts swelled the rubber strip to the point that they scalloped and no longer sealed in the washer spray.

I personally wouldn't try nitrile in this environment - preferring one of the Flurocardon grades (A,B,C Generic) available from DuPont.
If you are worried about its long term performance - why not bet a test beaker of the solution and leave a nitrile part in there ? If you want to get an accelerated life test - you could even heat it up
