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
