Specifications and performance

1) Elastic rubber sheet is a new type of rubber material by mixing EPDM, filler, plasticizer and other addition agent first then get vulcanized.

2)used on ballastless track, it can transfer horizontal and longitudinal load from the upper track effectively.

3)buffer horizontal and longitudinal force acting on grooves and convex plates.

4) It can reduce the restraint stress caused by temperature and contraction.
