Product description and Technical Specification
TECHNICAL DATA
Vibration insulation
Protrack Set
Left and right side profile for rail systems. produced using
fibres and granules of SBR
rubber (Styrene Butadiene Rubber) or EPDM rubber (Ethylene
Propylene Diene
Monomer) selected and compacted using polyurethane glue by
pressing process; 750
mm lenght, 800-900 kg/m³ density.
• Acoustic and electric insulation
• Easy to lay, to substitute and to maintain
• Protection of pavements for single or crossing tracks
Vibration insulation in railways and tramways
– Vibration and acustic rail insulation – Protection against
corrosion of the rails
