Nitrile Rubber (NBR) View Nitrile Rubber Products. Nitrile elastomers (NBR) result from reactions of butadiene and acrylonitrile (ACN) monomers. ACN content ranges from a high of about 50 percent to a low of about 18 percent. Available grades have approximately 50, 40, 30 and 20 percent ACN. The NBR blends well with many other polymers such as
