US 4,488,619 A · Foam-barrier-foam-facing acoustical composite

Abstract

A foam-barrier-foam-facing acoustical composite is disclosed having improved acoustical and flame retardant properties. The acoustical composite is a multilayered laminated fabric composed of: (a) a flame retardant polyvinyl fluoride facing layer; (b) a fire resistant acrylic adhesive layer bonded to the polyvinyl fluoride facing layer; (c) a first polyimide open cell foam layer bonded to the adhesive layer; (d) a noise barrier layer bonded to the first polyimide open cell foam layer, and (e) a second polyimide open cell foam layer bonded to the noise barrier layer.
