CNC Profile Cut Open Cell Melamine Treated Grey Acoustic Foam, 25kg / m3 Density Foam which has a controlled permeability and open cell structure that gives optimum acoustic performance for a foam of this density. Hardness 125 to 155 Newton's, Please note all polyurethane foam will react to UV light and can fade and yellow over time this however will in no way affect the foams sound absorption performance.
