| Acrylonitrile Butadiene Rubber (NBR) |
Acrylonitrile Butadiene Rubber, commonly known as Nitrile or Buna-N, is a combined polymer of Butadiene and Acrylonitrile. These are differentiated depending on the Acrylonotrile (ACN) content.
Low ACN polymers offer low temperature flexibility, compression set resistance and good elastic properties, but moderate resistance to oils and fuels. As ACN content increases, resistance to mineral oils, fuels and greases increases, but properties such as low temperature flexibility, compression set resistance and elasticity deteriorate. Medium ACN polymer exhibit good balance of all the above properties.
Normal service temperatures of these polymers range from -25ºC to 120ºC.
