Further Comments
At temperatures up to 100°C or, with special compounding, up to 120°C,
nitrile rubber provides an economic material having a high resistance to aliphatic
hydrocarbon oils and fuels. From the different grades available, the higher the
acrylonitrile (ACN) content, the higher the oil resistance, but the poorer the
low temperature flexibility. It has high resilience and high wear resistance but
only moderate strength. It has limited weathering resistance, and poor aromatic
oil resistance. It can generally be used down to about -30°C, but special
grades can operate at lower temperatures. | |

Acrylonitrile
Butadiene (NBR)
NBR
products have better oil stability with low absorption and expansion by hydrocarbon
oil, grease, solvent and fuel. This property is from the mixing with acrylonitrile,
butadiene and some additives. NBR can provide various grades of products with
use of wide range of ACN content, viscosity, emulsification additives, and stabilizing
mixtures.
