  • Performance and sustainability

    In addition to the performance of Amorim Tech Seal products, the choice of a solution based on cork and rubber was also motivated by the fact that cork is a natural and sustainable material. ​

    The sector has been increasingly focused on the end-of-life impact of vehicles, looking for materials that can be recycled and contribute to a circular economy, such as cork or the NRB composite, present in several references in the range.
