Wincell ultra-clean sound absorption board is a kind of general sound absorption material specially designed for different acoustic applications. It has excellent sound absorption performance and ACTS as a sound barrier (transmission loss). For the vibration problem, it can be used as damping and de-flow coupling (vibration isolation). With other materials such as perforated plate, aluminum plate and other composition of composite unit structure sound absorption effect will be better.

Application of sound-absorbing materials in mechanical equipment, sound-absorbing wall, sound-absorbing materials in sound enclosure/box.

★ Sound absorption

The open hole structure combined with the composite hole design can realize the effective absorption of air 

★ Sound in the wide band.

The unique combination of physical properties enables greater absorption at key noise frequencies (the absorption coefficient alpha ≥0.9 at 1000HZ and above).

★Sound barrier action (transmission loss)

The relative high density and high flow resistan
