Isomat (NR, BR & CR)

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.

Farrat Isomat was originally designed as a shock absorbing material for power presses but over the last 30 years it has demonstrated its capabilities in almost all areas including precision vibration control, high performance sound insulation, and Isolated Foundations. It is generally the place we start when designing a resilient support.

Isomat is available in 3 pure rubber compound types to suit the application:

• • IMNR 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
  • IMBR  (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
  • IMCR Chloroprene/Neoprene (IRHD Hardness: 45) sits between NR and CR in terms of damping if a compromise is required

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
