Products Description
Polyurethane Railway Tie Pad has excellent shock absorption performance and can effectively absorb the vibration energy generated during train operation, significantly reducing interference to vibration-sensitive areas along the line (such as hospitals, schools, residential areas, etc.).
Compared with traditional roadbed structures, its flexible material properties make trains run more smoothly, and it is particularly suitable for urban rail transit systems with high requirements for vibration control.

Product Advantages
01
Disperse stress to avoid wear and cracks on sleepers due to local stress
Railway sleeper pads are designed with polyurethane vibration-damping materials, which can effectively disperse the vertical load and impact force transmitted from the rails to the sleepers.
02
Reduce vibration to prevent premature displacement and pulverization of the ballast
It has good shock absorption performance, can buffer the high-frequency vibration generated during train operation, and prevent the vibration from being directly transmitted to the track bed structure.
03
Adapt to track deformation to improve the smoothness of train operation
Polyurethane Railway Tie Pad can timely adapt to slight track deformation, buffer structural stress fluctuations, and maintain the good geometric state of the rails, thereby ensuring the smoothness and safety of train operation.
04
Prefabrication to improve the efficiency of track construction
Sleeper pads can be prefabricated in factories in a standardized manner, reducing maintenance costs and improving operational efficiency.
