Rail pads are widely used in the railway fastening system. They are placed between the steel rail and the sleepers or tie plates for the purpose of eliminating the shocks and vibration caused by passing train. With the elasticity characteristics of rubber and eva and hdpe material, rail pad can keep the closed contacting with the rail above and the sleeper and tie plate underneath.
They are especially resistant to wear, shear, crushing, oil, greases, oxygen, and ultraviolet rays. Designed for service temperatures from -25ºC to 100ºC. For other temperatures, please consult us. Reduce noise and vibration:
Noise: typical reduction of 10% in dbA levels.
Vibrations: typical reduction of 48%.
Not only for the advantages of above mentioned points, the rail pad can perform the function as below:
