NBR (Nitrile, Buna-N)
Nitrile Buna-N is a co-polymer of acrylonitrile and butadiene.
The acrylonitrile content can be varied between 18% and 50%, the higher the acrylonitrile content, the better the resistance to oil and fuel, however, low temperature flexibility and elasticity will be compromised.
