Custom and standard multi-purpose rubber valves for various industries
Nitrile Rubber is a synthetic rubber produced by polymerization of acrylonitrile with butadiene. This 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 the year 2005, worldwide consumption of NBR had reached almost 368,000 metric tons annually.

• Nitrile Rubber belongs to the family of unsaturated copolymers of acrylonitrile and butadiene.
• The physical and chemical properties of this rubber vary depending on the polymer’s 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.
• These rubber is also resistant to aliphatic hydrocarbons.
• It is less resistant to ozone, aromatic hydrocarbons, ketones, esters and aldehydes.
• It has high resilience and high wear resistance but only moderate strength.
• 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.
