butyl aluminum alloy 1.8 is a butyl-acoustic insulation mat to improve the acoustics in the vehicle. The `unstable` coating is easier to put in motion, this increases the sound absorption and minimizes sound reflection. These sound absorption is an essential prerequisite for effective improvement of room acoustics. The thin foil is a higher absorption of sound energy causes because the thin coating better by the sound energy in motion and Thus the energy in the hydrodynamic boundary layer reacted much better to heat. This physical mechanism takes place in the immediate vicinity of the interface between the coating and butyl advantages.
