What Is Nitrile? A Guide to Nitrile O-Rings and Seals Nitrile, commonly known as NBR or Buna-N, is a synthetic rubber composed of acrylonitrile (ACN) and butadiene Based on the formulated ratio of ACN and butadiene, the working properties of nitrile seals may vary For example, lower ACN content equates to lower glass transition temperature, while hig
