Railway rubber pad, also called rubber rail pad, rubber tie plate. It is an important part of railway structure system, which is a kind of rail pad. Railway rubber pad is installed between steel rail and sleeper. The function of the railway rubber pad is to protect the sleepers from impacting and crushing. Meanwhile, the railway rubber pad can make the electrical isolation of the signal system. Due to the railway rubber pad be exposed to the atmosphere all the time, it requires a good resistance to natural aging, cold, and heat resistance. Besides, the railway rubber pad should have good shock absorption and low noise performance.
Along with the market of railway rubber pad is growing, there are more and more requirements for railway rubber pad.
The main material of railway rubber pad must be natural rubber or synthetic rubber, shall not use recycled rubber.
|number||Technical Parameter||unit||Technical Requirement|
|1||shore sclera scope hardness||℃||72～82|
|3||Elongation at break||﹪||≥260|
|4||200﹪tensile stress at a given elongation||MPa||≥9.5|
|5||EN Compression Set（100℃，24h）||﹪||≤30|
Air aging test（100℃，72h）
The static stiffness of the railway rubber pad shall be in accordance with the following table.
Static stiffness value（kN/mm）
The railway rubber pad should reach requirements have mentioned at least. In term of these requirements, AGICO Rail provides high-quality railway rubber pad. There are technical Parameters about our rubber rail pad.
|Hardness Shore A||℃||72-80 degree|
|Electronic Resistance||Ω||≥ 106|
|Tensile Strength before Aging||Mpa||≥12.5|
|Elongation before Aging||%||≥250|
According to these technical parameters, it finds that our railway rubber pad is certified product. On high-quality basis, we also provide different types of railway rubber pad.
