NBR (Nitrile, Buna-N)

Categories: ,


Nitrile, Buna-N is a co-polymer of acrylonitrile and butadiene.
The acrylonitrile content can be varied between 18% and 50%.
The higher the acrylonitrile content, the better the resistance to oil and fuel, however, low temperature flexibility and elasticity will be compromised.

Temperature Range

-40°C to +120°C


A good standard material which can be used across multiple applications. Please call for more information.


  • Good resistance to mineral and hydrocarbon based oil and fuels
  • Good resistance to certain dilute acid and alkali solutions
  • Good mechanical properties
