Sorbothane Vibration Isolators.
Sorbothane is a relatively new, high-tech synthetic material which, when correctly placed and compressed,
has the ability to reduce the vibrational coupling and mechanical shock between objects. It is increasingly used in the Hi-Fi arena as a
method of Loudspeaker vibration control.
A much fuller overview and tips on usage can be found in our article - How to use Sorbothane® Hemispheres.
It is recommended you view this article prior to making your choice of product.
Many other applications for Sorbothane are possible and some typical applications are found in Medical
and Sports footware, vibration and damping of heavy plant and machinery, Plant shock absorbers, isolation of delicate scientific instruments
and computer / Hi-Fi equipment such as in CD player trays, disc readers and loudspeakers.
Technically Sorbothane is a visco-elastic polymer, (basically a man-made chemical product),
which can be moulded into a variety of shaped products. The three basic shapes are Sorbothane hemispheres, strips and sheet.
It can also be punched into discs, doughnuts and more complicated shapes as required.
In the HI-Fi world, as a loudspeaker damping material, it is more commonly associated with
mechanically suppressing loudspeaker vibrations picked up by floor or air-borne disturbances.
The most used shapes for speaker damping are Sorbothane Hemispheres or Strips. The strips
may otherwise be known as isolation pads.
The Hemispheres shown below are available in a variety of sizes / diameters and grades of
stiffness, measured in Duro, 30 Duro being the softest and 70 Duro the hardest.
The tables provide a listing of our available products along with the recommended loading per
Hemisphere. Greater usage detail is in the Article.
There are few Adhesives which effectively stick to Sorbothane and therefore
the adhesives are moderately expensive.
By default the Hemispheres are supplied as NON-adhesive backed. If you wish to use Adhesive
backed items we can supply you with the necessary adhesive tape, (In strips), you get to be creative with the scissors.
Assorted Trial Sorbothane Pack.
A selection of Sorbothane hemispheres of different sizes and hardness,
giving the user the flexibility to trial different combinations / options of material characteristics at an
attractive price. 4 pieces each of the listed specifications equals one kit.
The 'Weight Range' covers four 'like' Hemispheres, 'equally', statically loaded.
The table indicates the Kit minimum weight loading for the smallest item to
the heighest weight loading for the Largest item. The individual item loadings are specified in the parts tables
against their part numbers.
Where there is component overlap in usable loading it is suggested the larger of the two
sizes is used as this provides for the maximum amount of interactive material to be used.
