Buna-N O-rings Special Compounds

Special Compounds in Buna-N Nitrile O-Rings

Nitrile rubber — also known as acrylonitrile butadiene rubber, NBR, or Buna-N — is a synthetically produced, petroleum-based rubber ideal for seals, gaskets and o-rings. Nitrile is a highly versatile rubber. It is used in countless applications and products, from marine fuel systems to small engine carburetors. Buna-N is currently one of the most widely used elastomers in the manufacture of seals.

While Nitrile rubber is considered to be a general purpose material for O-Rings and many other seals, it can be specifically compounded for many purposes.  Grades are available for: food processing, use with milk and edible oils, potable water and other specialty applications. Internal lubricants may be added to reduce frictional properties and extend wear. Specialty Nitrile polymers can be produced by carboxylation or hydrogenation HNBR.
