Moulding
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.
