Nitrile Extrusions

Nitrile Extrusions

Product Description

Acrylonitrile Butadiene Rubber (NBR) was the first oil-resistant synthetic rubber developed in Germany, in 1941. It was historically referred to as “Buna N” and is referred nowadays to as Nitrile rubber.

Nitrile is a very robust and highly oil resistant rubber that can be utilised in many industrial and heavy duty-based industries.

Please send us your design to see if we have a standard profile to match.

In the event we do not have a standard profile for your design then fear not. Our bespoke tooling service is the catalyst that will bring your design to life.


Typical applications for Nitrile Extrusion profiles include:

  • Door seals
  • Window seals
  • Hatch seals
  • Rubber bonding
  • Rubber to metal bonding


Features of our Nitrile Extrusions include:

  • Good bonding strength
  • Excellent resistance to hydrocarbon oils, fuels, and greases
  • Good hot air resistance (long term 90 °C, 40 days at 120 °C, 3 days at 150 °C)
  • Very low gas permeability
  • Moderate tear and tensile properties
