EVA Rail Pad is highly favored in the railway field due to its many high-quality properties.
Excellent cushioning and shock absorption performance is the outstanding advantage of EVA Rail Pad. When the train is running, the interaction between the wheels and the rails will generate strong vibration and impact force. EVA material can effectively absorb and disperse this energy with its unique flexibility and resilience. In high-frequency rail transportation such as urban subways, the use of EVA Rail Pad can greatly reduce the damage to the track structure caused by vibration, reduce the frequency of fastener loosening, and ensure the smooth operation of the train.

EVA Rail Pad has good weather resistance and temperature resistance. Whether it is hot and hot or cold and low temperature environment, it can maintain stable physical properties. On railway lines in cold areas, the temperature in winter is as low as - 30℃, and EVA Rail Pad will not become brittle and remain elastic; in the hot southern areas, when the temperature in summer exceeds 40℃, it will not soften and deform due to high temperature, always ensuring the stability of the track system.
In addition, EVA Rail Pad also has excellent chemical stability. It can resist corrosion from a variety of chemical substances and is not easily affected by rain, oil and other substances in the complex railway operation environment, which may cause performance degradation. This feature not only extends the service life of the Rail Pad itself, but also reduces the maintenance cost of the track system, further highlighting its value in railway construction and operation.
