Products Description
Polyurethane railway pads are high-performance components designed to provide superior vibration damping and noise reduction for modern rail systems. Made from durable and resilient polyurethane, polyurethane track bed damping pad play a critical role in enhancing track stability, protecting infrastructure, and ensuring passenger comfort.
GNEE RAIL Polyurethane railway pads adopt adjustable foaming polyurethane system and elastic bubble hole vibration damping technology to achieve a vibration damping effect of more than 12dB in track system.

Advantages
Advantages of Polyurethane track bed damping pad
01 Customized Stiffness Design
It makes full use of polyurethane microporous elastomer and geo-nonwoven fabric composite stiffness which can be designed to achieve the characteristics of "low load low stiffness, high load high stiffness", so that the vibration damping effect could reach ideal state under the premise of ensuring safety.
02 Thermal Compression Permanent Deformation
Due to the characteristics of polyurethane microporous elastomer raw materials and soft and hard section structure characteristics, its elasticity and toughness is excellent, so that the thermal compression permanent deformation is only about 7%.
03 Excellent Weather Resistance and Ozone Resistance Performance
The system does not contain unstable unsaturated double bonds, so that its heat resistance, water resistance, especially ozone resistance performance is excellent. (No cracking phenomenon)
04 Excellent Vibration Reduction Performance
Compared with ordinary elastic split fastenings without track bed damping pad, the vibration reduction can reach 12dB and above.
