Sorbothane®, a one-of-a-kind visco-elastic polymer that was first introduced in 1982. Since its introduction Sorbothane® has been used in many varied energy absorbing product categories. It can be – and has been – used in many different applications including everything from The Liberty Bell to the Air Force Memorial to Race Cars to the Space Shuttle. But Sorbothane is different than other shock absorbing materials like foam and rubber and we’d like to explain why.

Sorbothane is the best solution when you need a shock absorbing material Shock absorbing materials may be called shock absorbing polymers, visco-elastic polymers, visco polymers or simply polymers. There are many other shock absorbent materials available like rubber, neoprene, silicone, etc. but for our purposes here we’ll discuss polymer and Sorbothane specifically.

A good vibration isolation solution lowers the natural frequency of a system to below the excitation (or disturbing) frequency. Keeping these two frequencies “out of sync” eliminates resonance and greatly reduces the problems of vibration.

Vibration damping is a term that’s used in industrial, electronic and ergonomic applications when there is a need to reduce the amount of energy that’s produced by the system. Normally engineers try to address and reduce this energy at it’s source so the disturbing force is not at or near a natural frequency. This will ensure that resonance does not occur. Sometimes this is not possible for many reasons so problems will usually be controlled with a vibration damper. Usually when a good vibration damper is added, the energy that is left over is removed and converted to a small amount of heat which is referred to as the “swallowed energy”.

The more delicate parts that are included in a machine’s design, the more dangerous vibration can be. But, it is not always machinery that can be damaged by vibration. People can also find themselves troubled by unnecessary movements, causing them to look for personal use vibration solutions as well. A prime example is a shooter with his shotgun to his shoulder. The energy from the gun is transferred out the barrel but the recoil is sent directly into the shoulder, causing pain and in some cases may interfere with accuracy as well. In a lengthy shooting competition, that discomfort can become real, disabling pain.

Vibrations are all around us. They come at us in everything from the ground as seismic disruptions to external vibrations caused by automotive and air traffic – they are a constant in our lives. Moving parts within buildings, machinery, motors, tools, and electronics all create some form of vibration. Depending on your needs and goals these vibrations can be a major hassle so you need to find or develop the best vibration isolation system to subdue the undesirable movement. That’s where Sorbothane can help.

In engineering there is often a need to reduce the transmission of vibration between two elements while still maintaining mechanical support. Ultimately, the purpose of a vibration mount – and vibration isolation in general – is to reduce the effects of vibration and/or noise on people, equipment or the structure being engineered. A good vibration isolator lowers the natural frequency of a system to below the excitation (or disturbing) frequency. Keeping these two frequencies “out of sync” greatly reduces the problems of vibration.

Sorbothane combines shock absorption, good memory, vibration isolation and vibration damping characteristics all in one solution. In addition, Sorbothane is a very effective acoustic damper and absorber. There are many materials that exhibit one or more of these characteristics, Sorbothane combines all of them in a stable material with a long fatigue life.
