NBR Rubber

Oil and fuel resistant nitrile elastomer

NBR nitrile rubber bale in sealed polyethylene wrap

Product overview

Nitrile rubber is specified wherever contact with mineral oils, fuels and greases would swell or degrade a conventional elastomer. Its acrylonitrile content governs the trade-off between oil resistance and low-temperature flexibility.

We supply NBR across the common acrylonitrile ranges so that seal, gasket and hose manufacturers can pick the balance their service condition demands.

Key features

  • Strong resistance to mineral oils, fuels and greases
  • Good compression set behaviour in sealing service
  • Selectable acrylonitrile content for tailored performance
  • Reliable abrasion resistance in dynamic seals
  • Consistent Mooney viscosity for stable processing

Applications

  • Oil seals, O-rings and gaskets
  • Fuel and hydraulic hoses
  • Rollers, diaphragms and industrial linings
  • Automotive under-bonnet components
