Product Applications

Can be used in various applications with plywood, steel or aluminium base plates. Usually recommended for stiff structural applications, where unconstrained damping is unsufficient. Energy is dissipated as a result of shear deformation in the damping layer.

Material should have room temperature when cutting and during installation.

Light weight applications: Ventilation ducts, cabinets, noise enclusures, cabins.

Heavy duty applications: Bulkhead isolation, heavy constructions, thick steel panels. Wind-turbine generators, Marine & Offshore
