FC250

Trackelast FC250 is a natural rubber bonded cork, cellular product designed with specific static and dynamic stiffness properties together with low damping, to provide optimum vibration attenuation characteristics.

FC250 has been designed as an active vibration damping material in ballast mats, undersleeper pads and other resilient systems to reduce the propagation of vibration from rail tracks.
