Da/Pro Rubber Nitrile/Buna N/NBR

Da/Pro Rubber Nitrile/Buna N/NBR is a synthetic rubber comprised of a co polymer of acrylonitrile and butadiene. We use 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.

Polymer Name: Acrylonitrile Butadiene Rubber (NBR)

End Uses: Gaskets, Grommets, O Rings, Pipe Seals

Product Highlight

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. Our team 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.
