GRANUFLEX-RAIL vibration damping filler blocks for Vignol rail profiles (UIC54, UIC6, etc.)
GRANUFLEX-RAIL    vibration    damping    filler    blocks    are    made with   press   technology   from   rubber   granules   and   polyurethane binder. The    composition,    density    and    shape    providing    the    greatest noise   reduction   was   determined   by   testing   a   large   amount   of different samples. Thorough   development   has   resulted   in   GRANUFLEX-RAIL vibration       damping       filler       blocks       which       laboratory measurements   show   to   have   a   noise   reduction   effect   up   to 30dB.

The   filler   blocks   have   cut-outs   on   the   bottom   to   suit   the   spacing and type of different rail fastenings. The   vibration   damping   filler   blocks   are   fastened   to   the   rail   by adhesive or clips installed using a special tool.
