High-speed trains, which can travel more than 250 km / h, exert high dynamic forces on the rails. Instead of the conventional ballast rail bed, such loads require that the rails be mounted on a rigid concrete base with rail fastening systems that incorporate an elastic element (cushions or cushion) to absorb vibrations. This material has to absorb vibrations to prevent damage to the bed of the concrete rail, even after years of use in very hot, cold or wet environments. |  | |
Under Track Pad - Rail Baseplate The cushions or cushion form a resistant layer between the sleeper and the steel rail, which helps to prevent the cut of the sleeper, dampen the noise, dampen the vibration, its job is to diminish fatigue cracks in the concrete moorings, which they are accused by the impact and vibration generated by the passing of trains. The pads reduce shock or impact loads and reduce (by insulation and perhaps by damping) the resonant vibrations excited in the concrete sleepers. They also help reduce the loss of lag bolts, planks and track nails in the seat plates. To be highly resistant to ozone, chemicals and weather, maintain their properties regardless of the temperature -60 ° C to + 90 ° C. The rail pad, originally called the sole plate, is used especially when the rail is fixed to the concrete rather than when it is on sleepers or wood. The main function of the sleepers is to support the rails, transmitting the weight of the rolling stock to the ballast and, through it, to the ground. |  | |

TPC-ET Unlike foam, cross-linked polyurethane, which was widely used until now for similar applications, the TPC-ET and the foamed TPC-ET retains its resilience without hardening, whatever the weather conditions, anywhere in the world. It also resists the attack of fats and other products with which the fasteners of the rails can come into contact.
