Vibrafoam and Vibradyn

The material

Vibrafoam and Vibradyn are cellular elastomers and consist of a special polyetherurethane. Elastomer springs are used in mechanical engineering and construction for vibration decoupling. Vibrafoam and Vibradyn elastomers have excellent properties both as compression- and shear-loaded springs. Basic types with different properties are available for almost every application. They can be easily adapted to individual applications by selecting the Vibrafoam and Vibradyn types, the design and the contact surface.

The form factor

The stiffness or spring characteristic curve of cellular elastomers is not exclusively dependent on hardness and form factor, but also on the Volume compressibility. This plays a decisive, advantageous role, especially with large-area construction warehouses.

The damping behavior

Vibrafoam and Vibradyn materials have a built-in, defined damping. The damping behaviour of Vibrafoam and Vibradyn materials is described by the mechanical loss factor ŋ For Vibrafoam and Vibradyn materials these values are between 0.1 and 0.3. This means that under dynamic alternating load in Vibrafoam and Vibradyn materials part of the mechanical energy supplied is converted into heat. The advantage is that additional, complex damping elements can be dispensed with if the elastomer springs are suitably designed and designed. The risk of an infamous "resonance catastrophe" of a spring-mass oscillator is reduced.
