Rail rubber pad (also called rail pad) is made of elastic polyurethane pad and is installed between steel rail and concrete sleeper. It is an important part of the supporting structure of heavy crane rail tracks and railway tracks.
The function of railway rubber pads is to protect the sleepers from impact and extrusion. At the same time, railway rubber pads can electrically isolate the signal system. As railway rubber mats are always exposed to the atmosphere, they are required to have good resistance to natural aging, cold resistance, and heat resistance. In addition, railway rubber pads should have good shock absorption and low noise performance.
