What materials are typically used in rail pads?

 

Rail pads are typically made from elastomeric materials like natural and synthetic rubber, polyurethane, and thermoplastic elastomers (TPE). These materials are chosen for their ability to dampen vibrations, reduce noise, and withstand heavy loads and harsh environmental conditions. Composites and other specialized materials are also used for enhanced performance.

 

 

Rubber Rail Pad
Technical Parameter	Unit	Value
Stiffness	KN	90-130
Hardness Shore A	℃	72-80 degree
Electronic Resistance	Ω	≥ 106
Tensile Strength before Aging	Mpa	≥12.5
Elongation before Aging	%	≥250

 

• Rubber rail pads adopt synthetic rubber material, and possess high elasticity, wear resistance, aging resistance, and good weather resistance features.

 

• Their advantages are equipment with excellent capacity for damping effect, noise reduction, and adapting to extreme weather conditions.

 

HDPE Rail Pad
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 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.

 

EVA: Polyethylene 80%, Vinyl Acetate 20%.
Technical Parameter	Unit	Technical Requirement	Value
Density	g/cm3	0.95-0.98	0.95
Tensile Strength	Mpa	≥15	16
Elongation	%	>500	550
Melting Point	℃	170-190	170
Insulation Resistance	Ω	≥1×1010	5.0 ×1010
Hardness	A	≥90	92(A)

 

• EVA pad uses ethylene-vinyl acetate copolymer material, its features are high elasticity, wear resistance, aging resistance, and good shock absorption performance.

 

• As for EVA pads' advantages, EVA pads can absorb impact and shake, and reduce noise efficiently, thus improving the ride comfort.

 

As a professional rail fastener manufacturer, GNEE RAIL can produce various types of rubber rail pads with different materials, such as natural rubber, EVA, HDPE and so on. Our EVA/HDPE/rubber rail pads are with high elasticity, applying to types for rails such as rail UIC54, UIC60, BS80lbs,BS100lbs, and sizes as ordered. The pads can be customized with or without grooves, in various possible designs, depending on customers' requirements.

 

 

The Function of Rail Pad

 

• Distribute the load that the wheels pushed on the rails with a larger elastic surface.

 

• Reduce the noise and diminish the shock that trains hitting on the rails and improve the comfort of the passengers.

 

• The elasticity of rail pad can decrease the vibration that rails pass on the fasteners and the roadbed.

 

• The use of rail pad can decrease the abrasion of rails and prolong the service life of rail track and other rail fasteners.
