Material Properties and Vibration Isolation

General information on Sylomer®

Sylomer® is a special PU elastomer manufactured by Getzner, which features a celled, 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 moulded parts made of Sylomer® are also available.

For specific applications, special types can be manufactured with precisely defined stiffness. The material’s fine celled 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.

Quasi-static load deflection curve

Fig. 2 shows the typical pattern of the load deflection curve for Sylomer® under compression load.

In the lower load ranges, there is a linear relationship between tension and deformation. For elastic bearings, the permanent static load should fall in this range. The load range is specified in the individual data sheets.

After the linear load range, the load deflection curve moves on a degressive path; the material reacts to additional static and dynamic loads in a particularly “soft” manner, thus allowing for highly effective vibration isolation. In the data sheets, the area of the deflection
curve in which a high degree of efficiency is achieved with a relatively small degree of spring deflection, marked with the lighter shading in the diagram.
