Product Introduction

Kpsp polyurethane sleeper pad is a kind of customized elastomer. As a fixed elastic element at the bottom of the sleeper, it is employed to increase the vertical elasticity of the track bed, e.g. the ballasted track bed and the integral track bed in order to delaying pulverization and buffering the ballast and reducing the nosie pollution with a significant effect.

Key Parameters

1. Tensile strength ≥ 2.5 MPa;

2. Elongation at break ≥ 150%;

3. The thickness is 8 ~ 20mm, and the size can be flexibly designed as required;

4. The bonding force with the sleeper > 0.5 N/mm2;

5. Working temperature: -30 ~ 70 ℃.
