This presentation reviews the performance of ICI's latest range of acoustic foams with respect to airborne noise attenuation. These foams have been specially designed to provide not only low densities with excellent flow and demould times, but also the design flexibility to select the most appropriate intrinsic foam acoustic performance for the specific application under consideration.
