Rail Pad FC20

A high quality fl at rubber bonded cork rail pad based on a polychloroprene rubber blend, FC20 is designed with excellent strength and abrasion resistance, coupled with high resilience.

FC20 is used as a rail seat pad for use between flat bottomed rails and wooden sleepers. The polychloroprene formulation gives resistance to timber preservatives.
