NBR Acrylonitrile-buta-diene natural rubber
NBR nitrile rubber is a general term for acrylonitrile butadiene polymers. The content of acrylonitrile in nitrile seal mixtures substantially varies (18% to 50%) and the influence on the physical properties of the final material. The greater the content of acrylonitrile, the better the resistance to oils and fuels.
NBR rubber resistant to oil, especially hydraulic oil, gasoline, oil, and other aliphatic hydrocarbons, dilute acids, alkalis. It has good physical properties such as high resistance to friction, wear, and good resistance to temperature.
