CONIRAP – a complete system series of anti-vibration mats facilitates the elimination of noise transmitted from bogies of train sets ton surface and underground lines and thus contributes to the improvement of the environment. They can be used for gravel or concrete beds or for specifically modified systems intended for the installation on rails.

CONIRAP 0,1 S50

 

The CONIRAP 0.1 S50 anti-vibration mat is a sandwich-type product. It joins two different materials. The upper component is a CONIRAP 0.1 anti-vibration mat made of a rubber granulate, the lower component is a STERED ID 250 insulation board made of recycled synthetic textiles used in the automotive industry.
