High-Quality Plastic Parts from China Suppliers - Angle Gauge Plates, EVA Rail Pads, and More from Our Factory
Basic Information
These standard-compliant rail pads are core elastic components installed between the rail foot and base plate, responsible for absorbing wheel-rail impact, reducing vibration transmission and avoiding metal wear between contact surfaces.
Customized Materials
Mainly made of three customized materials matching different application demands: EPDM rubber for general heavy-haul and commuter lines, thermoplastic polyurethane (TPU) for 300km/h+ high-speed rails, and high-hardness nitrile rubber for North American 40t axle load heavy-haul freight lines as required by AREMA Chapter 5 specifications.
Core Performance
Fully meeting regional regulatory requirements: 25%~70% adjustable impact absorption rate, less than 10% permanent compression deformation after 10 million load cycles, operating temperature range from -40℃ to 70℃, and 500+ hour UV aging resistance for open-air lines.
Compatibility & Standards
Fully compatible with mainstream standard fastening systems including Pandrol Fastclip, Vossloh SKL series and AREMA tie plate systems. Customizable thickness, hardness and surface texture fit different rail profiles and gauge adjustment demands. Each batch includes material test reports and compliance certificates.
Frequently Asked Questions
What materials are the rail pads made of?
They are available in three customized materials: EPDM rubber for general heavy-haul and commuter lines, thermoplastic polyurethane (TPU) for 300km/h+ high-speed rails, and high-hardness nitrile rubber for North American 40t axle load heavy-haul freight lines matching AREMA Chapter 5 specifications.
What is the impact absorption rate and durability of these rail pads?
The rail pads feature an adjustable impact absorption rate of 25% to 70%. In terms of durability, they exhibit less than 10% permanent compression deformation after 10 million load cycles.
What are the environmental limits for these rail pads?
They are designed to operate reliably within a temperature range of -40℃ to 70℃ and possess a UV aging resistance of over 500 hours for open-air lines.
Which fastening systems are these rail pads compatible with?
They are fully compatible with mainstream standard fastening systems, including Pandrol Fastclip, Vossloh SKL series, and AREMA tie plate systems.
Is there a specific option for noise-sensitive urban transit lines?
Yes, low-damping customized versions are available for urban transit lines, which help reduce vibration transmission to surrounding areas by up to 15dB.
How is the quality control and compliance of the rail pads ensured?
Each batch is accompanied by material test reports and compliance certificates to meet local railway operation approval requirements.
