Rail pads are elastic polyurethane mats which are interposed between steel rails and railway sleepers to protect the sleeper top from wearing and impacting.
GNEE RAILWAY RAILWAYL have developed a range of high-performance elastic rail pads for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, especially those for E-type rail fastening systems and SKL type rail fastening systems with material of HDPE/EVA/Rubber.
The advantage of EPDM(rubber) rail pad
Exceptional Environmental Aging Resistance: Exhibits outstanding weather, ozone, extreme temperature, and chemical corrosion resistance.
High Performance Stability: Uniform molecular structure ensures low permanent deformation rate under long-term compression. Maintains durable elasticity and vibration damping effects, consistently cushioning wheel-rail impacts and distributing loads. Offers superior anti-creep and wear resistance.
Broad Application Scope: Suitable for high-intensity operational demands such as high-speed railways and heavy-haul lines. Reduces frequent replacements caused by material degradation.
