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
How to Make the Right Choice Between Viton® and Buna O-Rings Buna o-rings, however, are not suitable for ozone or weather exposure and will begin to degrade when exposed While both materials offer excellent capabilities and are similar in many ways, the key differences between the two are crucial when deciding between Viton® and Buna for your sealing application
AS568 Standard O-Rings - Apple Rubber Nitrile Buna-N: In the Nitrile family, you will find excellent compounds for fuel and oil applications For better ozone resistance, try Hydrogenated Nitrile (HNBR) Ethylene-Propylene: In the Ethylene-Propylene family, you will find compounds that are used extensively for outdoor, weather-resistant uses and water applications
NBR O-Rings: Everything You Need to Know - Official Apple Rubber Blog NBR, also known as Nitrile or Buna-N, is one of the most widely used and economical elastomers This material offers excellent sealing capabilities at a very low cost NBR is a copolymer of butadiene and acrylonitrile, and depending on the application, the proportions of acrylonitrile can vary from 14% to 50%
