Bondal® is a sandwich sheet, composed of two Galfan® galvanized steel plates (continuously hot dip galvanized steel with 5% aluminium) or aluminium plates (EN AW 5754 H12/H22) with a viscoelastic core layer.
The aluminium Bondal® plates are always provided of an one sided protection foil to prevent damage. The composition of the viscoelastic layer gives Bondal® a very high loss factor, which is shown in the graph. There are two standard types of Bondal® steel available.
The sandwich sheets can be cut, drilled, punched or sawn like normal plates. Distorting (bending, angle folding, scoring) the material is no problem if the sheets can move independently from one another. Mechanical connections can be applied without advance measures. There are guidelines for welding.
The product is mostly used as a low-noise (sheet) structure in:
Yachtbuilding and shipbuilding
Partition walls,floors and footbridges
Pipeline insulation and numerous other applications
