serilor® polyurethane for the rail industry

FIMOR has developed polyurethane compounds that meet the specific requirements of the railway industry (high speed, urban and interurban lines, metros, trams and maintenance), where all polymers are challenged by the exposure to heavy impact, severe shock, constant friction, and a wide variety of environmental conditions. Polyurethane elastomeric parts support heavy loads and protects the railway infrastructure against wear, noise, vibrations, and deformation. PU has effectively replaced both wood and metal in countless applications and can often be adhered to a wide variety of substrates. Cast urethanes have also found their way into the maintenance of rolling stock. It has a variety of possible applications in infrastructure, for the rolling stock and their maintenance. FIMOR has developed an internationally patented new generation of PU for use under sleeper pads (USP serilor® that reduce the necessity of very expensive periodic tamping. Field results show that Serilor® under sleeper pads have a lifespan equal to the concrete sleeper they support.

Examples of use: under sleeper pads ("USP"), protections for hopper wagons, under-rail pads, sheets for slab track, anti-vibration saddles, sleeper envelopes, wheel chocks, individual wheel protection, protections for off-rail storage of the axles, axle protections, customized parts for platform edges…
