A Farrat classic, Farrat Isomat is a versatile material that has proved to be a very high performance material in a wide range of construction and industrial applications.

Isomat is available in 2 pure rubber compound types to suit the application:

  • NR Isomat Natural Rubber (IRHD Hardnesses: 44, 50, 62, 70) has the highest resilience and lowest level of intrinsic damping so offers the highest level of vibration isolation coupled with low creep and long lifetime of any elastomeric material
  • BR Isomat (N)BR Rubber (IRHD Hardnesses: 40, 50, 70) has a high level of intrinsic damping meaning the degree of isolation will be less than NR but the damping can prove very useful for industrial applications

Each variant is available in 2 primary thicknesses (25, 50 mm) and 2 secondary thickness (20, 37 mm)

  • Load range: up to 1.4 N/mm² (SLS)
  • Vertical Natural Frequency: down to 6.6Hz
  • Average Damping Ratio ζ: 2 – 10%
  • Standard Sheet Size: 1000 x 500 mm
