Nirile in Caustic
Nirile in Caustic
(OP)
I previously posted this on the Polymer forum, but since there are some rubber experts here, I am inquiring here.I have an inline caustic washer on a paint line.The parts hang from an overhead conveyor and there is a slot on top of each stage for the parts hangers to pass through.This slot is sealed with a rubber strip on each side for the entire length.In the spray washer (5% sodium hydroxide at 140F)stage, I used EPDM rubber because of its resistance to hot water and caustic.But, I didn't consider the effects of the oil removed from the parts during washing.This oil mist swelled the EPDM sealing strips, scalloping them to the point where the top of the washer is no longer sealed.Would nitrile work in this application?
