The origin of NBR

Nitrile-butadiene rubber (NBR) was developed by the chemical company ‘I.G. Farbenindusty’ from Germany between WWI and WWII. At first the material was called Buna-N® and was later renamed to Perbunan®. The material first came to market in the 30s and is nowadays the most used elastomer for standard seals like O-rings and other seals.

What is NBR?

NBR is an elastomer, which is a synthetic polymer obtained by the copolymerization of acrylonitrile and 1,3-butadiene. The characteristics are partly determined by the amount of acrylonitrile in the material and this varies from 18 to 50 percent. As the acrylonitrile increases, resistance to petroleum base oils and hydrocarbon fuels increases, but low temperature flexibility decreases and the rubber can become brittle.

What is NBR used for?

  • Seals
  • O-rings
  • Gaskets
  • Pipe and Cable Covers

The advantages of NBR

  • Resistant against oils, fats, hydrocarbons, diluted acids
  • Has good mechanical qualities and is wear-resistant
  • Good resistance to heat
  • It is powerful and elastic
  • It has a working temperature range of -35°C tot + 120°C (-30 ° F tot + 250 ° F)

The downside of NBR

  • It has limited resistance to weather and ozone conditions
  • Not well resistant to aromatic compounds, halogenated hydrocarbons, ketone brake fluids and strong acids
  • Must be kept out of direct sunlight
  • The working temperature range is limited in comparison to other materials
