Competent solutions for noise and vibration insulation in rail traffic
DAMTEC® products consist of a special mixture of PU foam and high-quality rubber granules with a PU elastomer bonding agent i. e. from unused new raw materials. This leads to the desired properties and takes environmental protection into account. An aging of the rubber granulate is thus excluded. In particular, used tyres are not used here. With the extensively tested formulations, the products meet special requirements resulting from the loads in the track area. These elastomer materials are also used in other demanding areas such as building construction, civil engineering and tunnelling. Particularly noteworthy is the long-term behaviour, which guarantees a constant high level of effectiveness over decades. In this way, they efficiently counteract the multi frequency vibrations and shocks that are transmitted to the environment.
DAMTEC® applications and products
DAMTEC® MSS
Full surface bearings for mass-spring systems
DAMTEC® MSS products are decoupling and protective mats under rail systems tested according to DIN 45673-7 (Mechanical vibration – Elastic elements of the superstructure of rail tracks). They reduce structure-borne and secondary airborne noise and vibration emissions when used in „slab track“ (mass-spring system). DAMTEC® MSS products are supplied in rolls. Mats are available on request.
Products:
- DAMTEC® MSS K 10
- DAMTEC® MSS K 20
- DAMTEC® MSS K 23
Products with wave cut profile:
- DAMTEC® MSS K 17/8
- DAMTEC® MSS K 25/7
DAMTEC® SBM
Sub ballast mats
DAMTEC® SBM products are decoupling and protective mats under rail systems tested according to DIN 45673-5 (Mechanical vibrations – Elastic elements of the superstructure of rail tracks). They reduce structure-borne noise and secondary airborne sound as well as vibration emissions. In the case of ballasted track, the service life is extended by a lower and more uniform load. At the same time, they also protect engineering structures and seals.
Products:
- DAMTEC® SBM K 10 • K 10 V*
- DAMTEC® SBM K 20 • K 20 V*
- DAMTEC® SBM K 23 • K 23 V*
Products with wave cut profile:
- DAMTEC® SBM K 17/8 • K 17/8 V*
- DAMTEC® SBM K 25/7 • K 25/7 V*
* geotextile-laminated variant
DAMTEC® STM
Full-surface bearings for track slabs
DAMTEC® STM products are elastic separating layers for decoupling of track slabs. They are attached to both the plate sole and the conical grouting holes. This minimizes vibrations emitted into the ground. In combination with DAMTEC® STM, the slab becomes a lightweight mass-spring system with excellent structure-borne sound insulation.
