Nitrile Rubber (NBR)
Nitrile Rubber is a copolymer of butadiene and acrylonitrile used as a general purpose, oil resistant polymer in varying applications
The resistance of Nitrile Rubber to oil becomes more prevalent with the increase of nitrile in its make-up. This makes it the ideal copolymer for rubber seals and gaskets in the transport sector.
It is also widely used within printing rolls and hoses in a variety of industries.
What is Nitrile Rubber?
This material is also known as Nitrile-Butadiene, Acrylonitrile Butadiene or Buna-N. NBR is a copolymer made by reaction of butadiene and acrylonitrile.
Typically, NBR has a service temperature range between -40F and 275 F
In addition to oil, it displays excellent resistance to fuel, solvents, mineral and vegetable oils and hydraulic fluid. This characteristic may be coupled with a moderate ability to resist the exposure to ozone.
If an application demands resilience to petrol-chemical fluid, gasoline and/or grease, NBR is well suited for use as a rubber material. It is widely used if a customer requires a sealing type product as a result of this but also its wide temperature range.
Over 50% of the O-rings manufactured globally are made of NBR and this is a result of their use in many transport applications. Industrial and automotive industries use the material as part of their fuel and oil handling hoses, tubes, grommets and anti-vibration components.If an application requires a high grade NBR, this would usually indicate the product being produced is a gasket. This would be placed within a system such as a carburettor, fuel pump or perhaps an aircraft hose gasket.
Key NBR material features:
- Transport applications benefit from the oil resistant characteristics of nitrile rubber by using it for gaskets and seals
- Over 50% of the global manufacture of O-rings uses NBR
- Carburettors, fuel pumps and aircraft hose gaskets all use NBR as a sealing material
