Amorim Cork Solutions is introducing a new step in sustainable acoustic materials. Our Heavy Mass Layer, designed for high-performance damping and sound insulation, is now available in an FSC® certified version. This development reinforces our commitment to responsible sourcing and natural solutions for modern mobility…

Cork's air filled closed cell structure enables inherent damping of structural noise transmission, such as step noise and impacts throughout the decking surface and consequently increased acoustic performance.

Cork's air filled closed cell structure allows for inherent damping of structural noise transmission such as step noise and impacts throughout the decking surface and consequently increased acoustical performance.

When implemented correctly, it can significantly reduce noise levels, improve operating conditions and extend equipment life. One effective method to achieve structural attenuation is through the use of the cork-based compressed layer damping solutions developed by Amorim Cork Solutions. The effectiveness of a compress…

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 isolatio…

The performance of an isolation system is determined by the transmissibility of the system, the ratio of the Energy going into the system to the Energy coming out of the system. As a goal, vibration control design puts the disturbing frequency of the system in the isolation region The amount of damping in the isolation…

An insulation system’s performance is determined by its transmissibility, i.e. by the ratio between the energy introduced to the system and the energy leaving the system. Vibration control material is selected considering the placement of the system’s disrupting frequency in the insulation area. Additionally, the insul…

The electrical industry's commitment to developing safer and more sustainable equipment delivers many benefits for people and the environment, but also leads to new challenges in terms of vibration and noise control. Cork composite solutions offer various benefits to respond to these new challenges, since their natural…

This helps explain the enhanced durability and consistency observed in these composites. Several studies have investigated the mechanical behaviour of cork–rubber composites under various conditions. For instance, research published examined how the addition of cork to rubber compounds affects their mechanical properti…

Vibration isolation is the most effective way to reduce structure-borne noise. Cork-based materials are highly resistant and, in addition to enabling vibration insulation, they also have good damping effects. Indoor acoustic performance is a key factor in increasing quality of life and I believe that cork-based materia…

Rail pads, the elastic elements placed between the rail and the sleeper, play a critical role in load transfer, vibration control and the long-term performance of railway infrastructure. Their behavior depends mainly on two properties: stiffness, represented by the shear modulus, and damping capacity, expressed by the…

In the evolving landscape of rail infrastructure, the demand for sustainable, high-performance materials is vital. While often a “quiet” component in the system, the rail pad – sitting between the rail and the sleeper – is central to achieving high durability and lower environmental impact. Amorim Cork Solutions has de…

Equally important is the range of material combinations and thicknesses available. Railway infrastructure is subject to highly variable conditions, from differences in axle loads to environmental factors such as temperature fluctuations. By combining different material formulations, such as and natural and recycled rub…

Its negative carbon footprint, low thermal conductivity and sealing capacity, together with resistance to extreme temperatures and a high damping capacity are characteristics that make cork a raw material with enormous potential for this sector.  Cork combines its natural properties such as thermal insulation, fire ret…

AcoustiCork underscreeds are manufactured using a combination of natural cork and circular economy materials sourced from industrial waste streams, including recycled rubber granules (post-consumer waste) and polyurethane or EVA foams derived from pre-consumer industrial processes. These materials are combined through…

Rail pads are subjected to millions of load cycles over their lifetime. They need to remain resilient, maintain rail-seat stiffness, and resist environmental degradation. Cork–rubber rail pads excel in these areas thanks to their: ● High fatigue and aging resistance. ● Stability across a wide temperature range (−20°C…

Exactly. Cork has been used in the Energy sector for a long time, in particular in the T&D Transmission and Distribution area (Power or Distribution Transformers). Cork is used as a sealing element, where unique combinations of cork and selected rubber create materials suitable for flat sealing applications which,…

Technical Support: From Calculation Tools to Full Project Assistance Beyond materials and manufacturing, Amorim offers technical support and project assistance. Their in-house calculation tools, more specifically the Track Design Assistant (TDA), allow engineers to calculate the mechanical and acoustic behavior o…

Power transformers are often installed near residential areas, where strict noise requirements have been introduced. This has intensified the need to produce equipment that not only guarantees good long-term performance but also achieves greater vibration control and consequent noise reduction. It is often said that “j…
