Sorbothane Isolation Hemispheres

Article - overview and tips - How to use Sorbothane® Hemispheres.

It is recommended you view this article prior to making your choice of product.

      Sorbothane® is a relatively new, high-tech, synthetic material which has the ability to greatly reduce the transmission, (coupling) of vibration, between one / two vibrating objects. Transmission is the opposite of isolation, so the lower the transmission between items, the higher the isolation.

      It is used in a wide variety of applications which require isolation from shock and vibration. These applications include medical footwear, sports footwear, vibration damping of heavy machinery, isolation of delicate scientific instruments from noisy environments, top-end Hi-Fi equipment such as CD players, amplifiers and as loudspeaker mountings / feet.

      Technically, it is known as a visco-elastic polymer. Knowing what this means is not going to have much impact on your daily life, but . . . . . It's unique properties, those of performing somewhat like a solid and also as a liquid, make it a superb performer in the isolation stakes.

      Please read our Article - How to use Sorbothane® Hemispheres before making your choice.

      NB: This product, particularly the smaller items, look much like sweets, so it is important that they are kept away from children.
