Regupol® Elastomer Mats

Material Composition

Regupol® elastomers are composed of SBR and NBR rubber elements. For their production, rubber granulates, rubber fibres and rubber crumbs are combined with one another, processed and elasticised with various polyurethanes using a special manufacturing method.

Six different Regupol® elastomers are available for the daily requirements. They can be used in a very wide load range if required.

The Regupol® elastomers offer a solution that is technically sufficient as well as the most economical one available for most vibration-technology-related jobs.

Moreover, the BSW test lab offers the option of developing special, project- and application-specific types which can be given desired elastomer properties.

Regupol® elastomers can be distinguished from one another based on their individual load ranges and, accordingly, their dynamic rigidities.

Possible Uses

Regupol® elastomers are suitable for all different kinds of vibration isolation.

Due to higher dynamic rigidities and the admissible load ranges of some elastomer types, buildings and machine foundations can either be bedded elastically on strips or on delicate point supports. Due to the low support frequencies, this type of support is technically efficient, but more difficult to plan and execute. The majority of isolation jobs are performed on full-surface Regupol® elastomers with lower rigidity, because this is more feasible and less error-prone.

The technical details, clearly arranged and determined as well as tested by the Technical University Dresden, provide a full overview of the load range of the Regupol® elastomers and their non-linear material properties. They allow expert consultants to select and properly size the elastomer type that suits the situation at hand and meets its respective requirements.

Additional benefits of Regupol® elastomers are their excellent moisture resistance, their rot-proof properties, their ozone resistance and their permanent elasticity even after frost-thaw cycles.

The use of Regupol® is therefore admissible not only inside but also outside of buildings.

Effectiveness of the Regupol^® Elastomers

Regupol® elastomers can be specifically set for support frequencies between 20 Hz and 10 Hz in a broad load range from 0.005 N/mm² to 1.5 N/mm². Expert consultants in particular benefit from this large degree of flexibility.

The natural frequency progressions of the Regupol® elastomers are benign, offering expert consultants nearly constant natural frequencies across a wide load range. This makes for a large degree of security in planning and execution.

The creep (or creep behaviour) is low for all different Regupol® elastomers at approx. 5−7% of the total thickness. The admissible permanent load limits are kept, the only effect of overloading on the elastomers is increased rigidity (rise in dynamic rigidity and natural frequency), which shows in progressive deflection.

Regupol® elastomers are produced and shipped in rolls. They can be cut to size with a standard utility knife right at the construction site. The professional company at the construction site is thus ensured that the installation is going to be simple, quick and cost-efficient.
