Railway pads always play a key role in rail fastener system. It's a bedding device between the rail track and the railway sleeper (or railroad tie), which ensures the railway safely and stably operates by providing cushion and support.
HDPE pads have high strength, wear resistance, aging resistance, and good weather resistance features.Simultaneously, they possess durability, lightweight, easy-to-process, and easy-to-install advantages.
The following are the HDPE pad detailed parameters:
| Technical Parameter | Unit | Technical Requirement | Value |
| Density | g/cm3 | 0.95-0.98 | 0.95 |
| Tensile Strength | Mpa | ≥19 | 19 |
| Elongation | % | >80 | 150 |
| Melting Point | ℃ | 170-190 | 190 |
| Insulation Resistance | Ω | ≥1×1010 | 3.5 ×1010 |
| Hardness | A | ≥98 | 98(A) |
HDPE pad uses
Based on HDPE pad features, HDPE pads are suitable for railways with high load capacity requirements, and they perform especially well in high or low-temperature environments.
Generally, HDPE pads are widely used in high-speed railways, heavy haul railways, and mainline railways, and they are suitable for E-type, SKL, KPO standard rail fastening systems.
