Nitrile Rubber (NBR)

Nitrile Rubber (NBR)
Nitrile Rubber Sheets
Nitrile Rubber is a synthetic rubber produced by polymerization of acrylonitrile with butadiene. Nitrile synthetic rubber is also known as NBR, acrylonitrile-butadiene rubber, acrylonitrile rubber, nitrile-butadiene rubber, and NR. This type of synthetic rubber is widely used in a number of applications. In fact, industrial nitrile rubber is one of the very sought after variety of synthetic rubber by most of the manufaturing units. In the year 2005, worldwide consumption of NBR had reached almost 368,000 metric tons annually and the global market for nitrile butadiene rubber has been forecast to exceed 645 thousand tons by the year 2017.

What is Nitrile Rubber (NBR)?

Nitrile rubber or NBR is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. The chemical name of nitrile synthetic rubber is acrylonitrile-butadiene copolymer. It is one of the important synthetic rubber types having a high resistance to aliphatic hydrocarbon oils and fuels. There are different grades available with nitrile rubber manufacturers and suppliers. The higher the acrylonitrile (ACN) content in a grade of nitrile rubber, the higher will be the oil resistance but then the low temperature flexibility will get poorer.

Nitrile Synthetic Rubber Properties

Nitrile rubber has high resilience and high wear resistance. However, it has only moderate strength along with limited weathering resistance and poor aromatic oil resistance. Nitrile rubber can generally be used down to about -30C but special grades of NBR can work at lower temperatures too. Following is the list of Nitrile Rubber Properties.

Applications of Nitrile Rubber

NBR or the nitrile synthetic rubber is considered the workhorse of the rubber products of the automotive and other industrial units. By selecting an elastomer with the appropriate acrylonitrile content in balance with other properties, industrial nitrile rubber (NBR) is used in a wide variety of application areas requiring oil, fuel, and chemical resistance. In the automotive area, NBR is used in water handling applications and in fuel and oil handling hose, seals and grommets. With a temperature range of –40 to +125 degree celcius, NBR materials can withstand all automotive applications. This form of synthetic rubber because of its resilience is the perfect material for disposable lab, cleaning, and examination gloves.
