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.
