Soundfoil LT
Soundfoil LT is a constraining layer vibration composite, consisting of an outer constraining layer of thin metal (typically aluminum) and a viscoelastic polymer coating with a removable release liner.
Soundfoil LT reduces structure-borne noise resulting from unwanted vibration, impact, resonance and coincidence problems in thin gauge metals or structures by dissipating vibration energy.
Soundfoil LT is unique in its ability to provide high loss factor and smaller shear modulus over a wide temperature range of -40° to 27° C (-40° to 80° F) – with sizeable damping down to -40° being particularly significant. This is maintained over long-term aging at a recommended service temperature ranging from -60° to 66° C (-76° to 150° F).
Soundfoil LT has good resistance to water, common solvents, corrosion, cyclic heating and cooling, and outdoor weathering.
