NBR 80 Shore


Among standard seals such as O-rings and radial shaft seals, NBR is the most widely used material. The reasons for this are good mechanical properties, high abrasion resistance, low gas permeability and the high resistance to mineral oil based oils and greases. NBR is a copolymer of butadiene and acrylonitrile. Depending on the application, the content of acrylonitrile can vary between 18% and 50%. Low ACN content improves cold flexibility at the expense of the resistance to oil and fuel. High ACN content improves the resistance to oil and fuel while reducing the cold flexibility and increasing compression set. To obtain balanced properties, our standard NBR materials have an average ACN content around 30%.


NBR has good resistance to:


  • mineral oil-based oils and greases
  • aliphatic hydrocarbons
  • vegetable and animal oils and fats
  • hydraulic oils H, H-L, H-LP
  • hydraulic fluids HFA, HFB, HFC
  • silicone oils and silicone greases
  • water (max. 80°C)


NBR is not resistant to:


  • fuels with high aromatic content
  • aromatic hydrocarbons
  • chlorinated hydrocarbons
  • non-polar solvents
  • hydraulic fluid HFD
  • glycol-based brake fluids
  • ozone, weathering, ageing
