Nitrile/Buna N/NBR

Nitrile/Buna N/NBR

Da/Pro Rubber can custom compound a variety of rubber materials. Nitrile rubber or Buna-N is a synthetic rubber comprised of a copolymer of acrylonitrile and butadiene. Da/Pro uses trade names such as Nipol, Krynac, and Eroprene but can also custom compound Nitrile for nitrile rubber o-rings, nitrile gaskets or other nitrile rubber molding components.

Acrylonitrile butadiene rubber (NBR) is a family of nitrile rubber whose physical and chemical properties vary depending on the composition of acrylonitrile. The more acrylonitrile that is in the polymer the higher the resistance to oils but the lower the flexibility of the material. This makes NBR generally resistant to oil, fuel and other chemicals. Da/Pro Rubber has molded custom nitrile rubber for seals, grommets, nitrile gaskets, and nitrile o-rings. 

Nitrile rubber is more resistant to oils and acids compared to natural rubber but is not as strong or flexible. Like natural rubber it can be attacked by ozone, aromatic hydrocarbons, ketones, esters and aldehydes but is generally resistant to aliphatic hydrocarbons.
