Corrosion protection: all DSD-type vibration damper springs have cataphoretic coating (KTL).
The main part of this element is a damping insert made ​​of special polyurethane elastomer Sylomer (Austria), which corresponds exactly to the stiffness of the spring.

Damping material is elastic and resistant to breakage. To reduce the transmission of structure-borne noise to the supporting frames of structures and buildings Vibrofix Spring 1 DSD spring vibration dampers can additionally be completed with elastic gasket of polyurethane elastomer
