So, what makes Nitrile Rubber (NBR) unique?Nitrile rubber, also known as NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene.
Although its physical and chemical properties vary depending on the polymer’s composition of nitrile, this particular type of synthetic rubber is unusual in being generally resistant to oil, fuel, and other chemicals. So, the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material.
Nitrile is the most widely used elastomer in the seal industry today. It is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks, since ordinary rubbers cannot be used. NBR’s ability to withstand a range of temperatures from -40 to 108 °C (-40 to 226 °F) makes it an ideal material ...
