Acoustic Materials - Anti-Drumming Ampere Audio Vibraflex Extreme® Vibraflex is a self-adhesive anti-drumming and insulation plate made of very flexible bitumen synthetic and special fillers. The plate combines a high specific mass with a high internal damping. Besides anti-drumming, also an increase in airborne sound insulation is realized. Vibraflex is provided with a laminated PE-foil on the visible side for protection against influences from oil, fuel, etc. Applications Vibraflex i s a u n i v e r s a l l y a p p l i c a b l e Anti-drumming and insulation material for surfaces of sheet steel, aluminum, wood and plastic. Because of its suppleness Vibraflex is especially suitable for application on the inside of noise insulating casings for conduits. Sound insulation The sound-insulation is shown in the chart in the graph below, the improvement of air sound insulation value R of Vibraflex bs 50, bs 80 and bs 100 is shown as a function of the frequency, measured according to eN 20140. The graph on the back shows the damping (loss factor), measured according to eN 6721-3. Shape, appearance and color Color of the sheet: black Vibraflex® Composition Vibraflex basic consists of four layers, see picture. The adhesive glue (based on solvent free acrylic copolymer) attaches very well to a painted and unpainted (smooth) surface. Anti-drumming plate, which Resistance to liquids The anti-drumming plate is resistant to water and oil. It is not resistant to fuels and solvents.
