Nitrile Rubber Sheets
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
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
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
- Nitrile Rubber belongs to the family of unsaturated copolymers of
acrylonitrile and butadiene.
- The physical and chemical properties of nitrile rubber vary depending
on the polymers composition of acrylonitrile.
- Different grades are available for this rubber. The higher the
acrylonitrile content within the polymer, the higher the oil resistance.
- It is generally resistant to fuel and other chemicals.
- It can withstand a range of temperatures.
- It has inferior strength and flexibility, compared to natural rubber.
- Nitrile rubber is also resistant to aliphatic hydrocarbons.
- It is less resistant to ozone, aromatic hydrocarbons, ketones, esters
- It has high resilience and high wear resistance but only moderate
- It has limited weathering resistance.
- It can generally be used down to about -30 degree celcius , but
special grades can also operate at lower temperatures.
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.
