1.Function: to low-frequency vibration isolation 2.Usage: rubber pad under railway concrete sleeper. 3.ISO9001:2008

 Black turnout  rubber pad under  railway concrete sleeper track . 

Application:

This kind of rubber pad used on  Channel Sleepers on Bridges, Turnouts, Rail Expansion Joints and running rails tracks . it's can impact the energy and ease the impact on the primary purpose of the role of the rubber products.  dynamic stiffness is greater than the static stiffness, helps to reduce the impact of deformation .
