920 (0.128 - 1.128 MPa, 2Hz) 12mm sample thickness |
Baseplate pad providing a resilient interface between rail chairs or baseplates and concrete or steel sleepers. It is also used for continuous rail support in embedded rail systems. Where maximum electrical resistance is important the pad can be supplied with a 1mm thick highly insulating layer bonded to the top surface. |
FC26 | More Info | 80 | 1.20 | 12000 (0.128 - 1.128 MPa) 5mm sample thickness |
N/A | Specially formulated for use in maintenance bays and vehicle washing plants where heavy contamination with lubrication, fuel oils, cleaning chemicals and other aggressive contaminants is present. |

790 (20 - 80 kN, 5Hz) 4.5mm sample thickness |
Used as a rail seat pad for use between flat bottomed rails and wooden sleepers. The polychloroprene formulation gives resistance to timber preservatives. |
FC105A | More Info | 90 | 1.00 | N/A | N/A | Rail seating pad material originally developed for use as a continuous support strip on paved concrete track (PACT). It can also be used between either flat-bottomed rails and concrete sleepers or flat-bottomed rails and malleable iron or steel baseplates. |
FC584 | More Info | 60 | 1.05 | 190 (20 - 80 kN at 1200 KN/min) 10mm sample thickness |
N/A | Used as a rail seat pad material, for use between either flat-bottomed rails and concrete sleepers or on malleable iron or steel baseplates. It is designed for maximum axle loads of 25 tonnes and speeds up to 250 KM/hr. |
FC892 | More Info | 65 | N/A | N/A | N/A | FC892 can be used either as a baseplate pad or as continuous rail support between flat bottomed rail and concrete slab track. It is designed to have excellent resilience, damping and impact attenuation properties for axle loads up to 25 tonnes. |
Micromax (Rail Pad) | More Info | 53 | 0.97 | 140 (20-80 kN) 5.5mm sample thickness |
260 (20-80 kN 5Hz) 5.5mm sample thickness |
Reduces dynamic forces from the track into sleeper systems. In this way it is possible to give older sleeper designs modern levels of impact protection. Micro-max pads are also available for new build track. |
Micromax (Baseplate) | More Info | 50 | N/A | 48 (8 - 70.5 kN) 10mm sample thickness |
60 (8 - 70.5 kN, 2Hz) 10mm sample thickness |
Considerably reduces dynamic forces from the track into sleeper systems, and are suitable for both modern high speed systems and for upgrading older track designs. |
