Dynacast Industrial Products Nitrile Rubber - NBR

Dynacast Industrial Products Nitrile Rubber - NBR is copolymer of butadiene and acrylonitrile. With Nitrile rubbers, the oil resistance increases as the acrylonitrile content but at the expense of resilience. NBR has good oil and liquid fuel resistant and good gas barrier properties.

Polymer Name: Acrylonitrile Butadiene Rubber (NBR)

End Uses: Gaskets, Industrial Applications, O Rings

Features: Acid Resistant, Gas Barrier, Good Compression Set, Good Strength, High Resilience, Oil Resistant, Tacky, Tear Resistance, Water Resistant, Wear Resistant

Product Highlights

At temperatures up to 100C, or with special compounding up to 120C, nitrile rubber provides an economic material having a high resistance to aliphatic hydrocarbon oils and fuels. Different grades are available - the higher the acrylonitrile (ACN) content, the higher the oil resistance but the poorer is 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 -30C, but special grades can operate at lower temperatures.
