Vibration Isolation

A specific material formulation for vibration isolation which allies performance with environmental concerns

Urbanisation is a megatrend, one of the major pathways of development

With it, the importance of quality acoustic environments for human well-being continues to grow. People around the globe are more aware of the impact that acoustics have on their daily lives and expect higher quality acoustic experiences. On the other hand, trends in sustainability, recycling and circular economy require greater focus on minimizing waste and environmental impacts. Amorim’s cork-based solutions for acoustic noise and vibration isolation represent progress in responding to these three megatrends.

 Acousticork Vibration Control materials are engineered compounds of cork, natural and/or recycled rubber. With high loss factors, essential to the damping function - due to cork's closed cell structure filled with air, it dissipates vibration energy into low grade heat in each vibration cycle, resulting in a low amplification at resonance, giving our materials operational effectiveness in a wide range of frequencies.

  • Maximizing comfort and protecting equipments

    Isolating the source of the vibration is essential not only to protect the quality of life of people in both the immediate location and those in the surrounding environment, it also helps to protect equipment from the long term degenerative effects of vibration. Acousticork Vibration Isolation range allows to achieve better performance results in a wide range of applications.

  • Cork composites for high performance

    While cork has a higher loss factor than rubber – which is essential to the dampening function and consequent dissipation of energy – anti-vibration rubbers are isolative and offer very little damping. The combination of these two materials as a cork rubber composite brings added characteristics as a vibration isolation material.

    No material combines performance and process handling with such perfection and variety, adding resistance to mechanical and thermal effects, as well as chemical compatibility, in products which are easy to cut and shape into the final application.
