Need some help with Nitrile.
Need some help with Nitrile.
(OP)
It would be fair to say that rubber is not my field of expertise. I have recently been part of completing a project for a client that requires mineral oil and rubber. I was made aware that natural rubber, as well as many other synthetic materials were not compatible with mineral oil. Having researched it I purchased some nitrile rubber to use as a sealant, under the impression that it would not react. After a few days I noticed that the oil near the rubber was turning a yellow colour. Thinking it might have just been a chemical used to treat the rubber I drained the oil and topped it up with a fresh batch. Once again it turned yellow. Would anyone be able to shed some light as to what is causing the discolouration and if there's anything I can do to prevent it from happening any further?
TLDR: Is it normal for nitrile to leak yellow into mineral oil and can it be prevented?

I assume you just bought some NBR off the shelf. If you contacted a rubber part manufacturer, and described your problem, perhaps they could get you some NBR that wouldn't have the tendency to discolor the oil.
