MAFUND® insulation counters mechanical vibration and structure-borne sound
PRODUCT BENEFITS AND USE
MAFUND® plates are installed under machines, appliances, pumps, structural components and similar or below their foundations to provide protection against shocks and tremors, vibration and structure-borne sound. They consist of a highly elastic rubber compound with exceptional ageing and weather-resistance properties. The plates can be used without restrictions within a temperature range of -20°C to +80°C. The vibration insulation effect achieved with these plates is based on the elimination of periodic or abrupt shocks emanating from the disruptive source in these plates, thus reducing the transmission of vibration and structure-borne sound considerably. MAFUND® plates can be cut to the desired format. Two or more plates can be glued together if necessary to achieve a higher degree of resilience.

Product explanation
Function
The action of vibration insulation in conjunction with MAFUND® plates is based on the elimination of periodic or abrupt excitation emanating from the disruptive source in these plates, thus reducing the transmission of vibration and structure-borne sound considerably.
Advantages
• MAFUND® plates consist of a highly elastic rubber compound with exceptional resistance to ageing.
• The temperature range lies between -20°C and +80°C.
• MAFUND® plates are resistant to the effects of weather.
• The material insulation achieved by the MAFUND® plates reduces vibration amplitudes and the transmission of force when starting up and shutting down the machine (resonance passage) and shortens decay processes during impulse excitation.
• The high degree of resilience of MAFUND® plates means that the laying of strips (partial surface occupancy) is adequate in the majority of applications. This enables the optimum adaptation of elastic mounting to specific requirements and achievement of a maximum insulation effect through elastic mounting with a minimum use of material.
• In contrast to full surface mounting, the configuration of MAFUND® plates during strip laying can be coordinated with the centre of gravity of the system, thus avoiding variations in deflection and an inadequate insulation effect.
• The high static friction of MAFUND® plates means they can be installed in the majority of cases without additional fastening.
• Decades of experience have been gained in this area.
Structure
Where the machine or its base frame possess an adequate level of torsional rigidity, the MAFUND® plate can be placed directly below the machine. Where torsional rigidity is inadequate, an intermediate foundation or base frame with adequate flexural and torsion resistance is required. Insulation through an intermediate foundation is the classic insulation technique for reducing vibration and structure-borne sound transmission and achieves the best insulation effect.
Selection criteria
Necessary dimensions are determined relative to the required natural frequency, the permissible distributed load and the available support surface and number of supports. MAFUND® plates are also arranged in several layers to achieve the required natural frequency and the greatest possible insulation effect.
