Nitrile (BR)

A high performance vibration and shock damping material with excellent chemical resistance to industrial fluids. The BR compound is the same material used in Isomat BR.

Nitrile (BR) is a versatile anti vibration material used predominantly in industrial applications

  • Load range: up to 1.8 N/mm² (SLS)
  • Vertical Natural Frequency: down to 15Hz
  • Average Damping Ratio ζ: 8.5 – 10%
  • Standard Sheet Size: 1000 x 500 mm

Why choose Farrat Nitrile (BR)?

  • High resilience
  • High damping
  • Low level of creep
  • Tread pattern improved grip and dynamic performance
  • Manufactured by Farrat in UK
  • Can be supplied as full sheets, cut to size pads and strips (including holes and slots if required) according to the customer’s requirements.


  • In low pressure applications it may be necessary to consider alternative materials such as Farrat Isomat Nitrile IMBR. Farrat are happy to advise and provide technical calculations to specify the most appropriate material.
  • Where bolt through connections are required, Farrat Anti-vibration (AW) washers and bushes should be incorporated in order to allow free movement of the pad and to ensure that the bolt does not transmit vibration across the connection.

Typical Applications
Note: These applications are a guide based on typical examples that we see regularly. The ideal material will depend on the specific characteristics and constraints of your application.
