All our anti-vibration devices use a proprietary Visco-Elastic Polymer that flows like a liquid under load. Combining this fast-reacting, high-energy motion absorption with a nearly faultless, long memory guarantees that this polymer will outperform and outlast any other material, including any one-dimensional solution such as rubber or springs, which are often employed to reduce vibration. Rubber's resiliency is particularly short lived, and springs lose their efficiency just as fast.
