Applications:These foams offer good sound absorption performance, are moderately cost effective but have a short life if exposed to UV or weathering.their open cell structure absorbs water and some specific references allow water or air filtration (PPI foam).Polyurethane foams can be treated by impregnation, in which case they are used to seal against air and driving rain, mainly in buildings, and are therefore pre-compressed. Characteristics: Polyurethane foams can be recycled to produce Agglo foam, which is used for its soundproofing and impact protection properties.NON-CONTACT VISUAL.
