Can you give more infomation?  NBR to me means Nitrile butadiene rubber.  Is this what you are asking about?

Thanks.

The best people to answer this question are the polymer manfucturers.  They usually have technical assistance departments that will answer these questions. 

The problem is getting to them.  It will usually take multiple phone calls and transfers.

NBR is usually solvent resistant.  Can't tell you specifically about the H2S, though.

Good luck.
