Acoustic and vibration isolation in rail traffic
Elastic bearings made of polyurethane
KRAIBURG PuraSys, as part of the KRAIBURG Holding, specializes in sub-ballast mats, bearings for mass-spring-systems and other special elastic supports made of polyetherurethane in the railway superstructure. KRAIBURG PuraSys has already successfully established itself on the international market through numerous projects with its PU products for solving noise and vibration problems caused by rail traffic. KRAIBURG PuraSys is of course ISO 9001 certified and thus guarantees high quality and complete traceability of its products. PuraSys PU elements are tested according to DIN 45673-5, DIN 45673-7 and other national as well as international standards. Quality products – produced in harmony with nature Environmental protection is a key strategic task at KRAIBURG PuraSys.

PURASYS products for track construction are made of high-quality elastomer materials. With the extensively tested formulations, the products meet special requirements resulting from the loads in the track area. PURASYS products are produced in the form of mats and stamped or water cutted parts and are therefore suitable for point bearings, strip-like support or full-surface bearings. These elastomer materials are also used in other demanding areas such as building and tunnel construction. Particularly noteworthy is the long-term behaviour, which guarantees a constant high level of effectiveness over decades. In this way, they efficiently counteract the multi-frequency vibrations and shocks that are transmitted to the environment.
