Railway rubber pad is an important part of the track structure. It is installed between the rail and the concrete sleeper. Its main function is to buffer the high-speed vibration and impact generated when the vehicle passes through the rail, protect the road bed and sleeper, and carry out the electrical insulation of signal systems. And long-term exposure in the atmosphere, railway rubber pad is required to have good resistance to natural aging, cold and heat. The rubber pad for subway has a good performance of low noise absorption.
Railway rubber pads have good vibration damping, anti-aging, abrasion resistance, stability, and strong resistance to high and low temperature. The material is composed of natural rubber, SBR, neoprene, HDPE, EVA, high-density polyethylene and other combinations, so the railway rubber pads have good flexibility, and it's not deformed or broken easily at various temperatures.
Railway rubber pads have the advantages of long life cycle, low costs for maintenance and replacement.
