SYLOMER® VIBRATION ISOLATION

Sylomer® is a special PUR elastomer manufactured by Getzner, which features a cellular, compact form and is used in a wide range of applications in the construction and mechanical engineering industries. In most cases, Sylomer® is used as a compression-loaded elastic support element. The characteristics of the elastic support can be adjusted to the structure, construction method and load requirements by selecting the specific type of Sylomer®, the load-bearing area and the thickness.

Sylomer® materials are available as a continuous roll and are particularly well suited as flat, elastic layers. Above and beyond this, engineered moulder parts made of Sylomer® are also available.

For specific applications, special types can be manufactured with precisely defined stiffness. The material’s fine cellular structure provides the necessary deformation volume under static and dynamic loads. As a result, elastic bearings with full-surface load transmission are possible. This offers major engineering and economic advantages, especially in the construction industry.

Loss Factor

When Sylomer® materials are subjected to dynamic loads, some of the mechanical work applied is transformed into heat by dampening effects. The dampening behavior of Sylomer® materials can be described by the mechanical loss factor, which ranges between 0.09 and 0.25 for Sylomer® materials. The specific values are shown on the product data sheets.

Behavior With Shearing Loads

Fundamentally speaking, a Sylomer® bearing is softer with regard to shearing loads than with regard to compression loads. The relationship of compression to shearing stiffness ranges between factor 4 and 10, depending on the cellular structure and geometry of the Sylomer® bearing. The quasi-static shearing delection curve exhibits relatively linear deformation behavior.

STATE-OF-THE-ART SOLUTIONS

Specialist skills and industry-wide experience have made UK-based TVS Acoustics a leading player in two of the most demanding markets for acoustic flooring – cinema and bowling alley construction projects. Both require state-of-the-art solutions, which TVS Acoustics is well placed to provide thanks to nearly two decades of work across the entertainment sector and fields ranging from theatres and gyms to commercial and residential buildings.
