Fire protective compositions include colloidal silica solids, clay, a low biopersistence fiber or refractory ceramic fiber, water, and optionally a chelating agent. Methods of using the fire protective compositions include providing a polymeric foam substrate, applying the fire protective composition on the polymeric foam substrate, and allowing the fire protective composition to dry.

A vehicle interior panel includes a decorative skin layer and a backing layer. The backing layer can include a barrier material that helps prevent outgassing of a plasticizer of the decorative skin layer in a direction toward an underlying substrate of the panel. The backing layer can be formed by vacuum coating and/or formed while a slush molded layer remains on a slush molding tool surface on which it was formed. in some cases, a slush molding tool thus finds new uses in a vacuum coating process or in some other process apart from slush molding.

Described herein is an acoustic structural panel having a first exposed major surface opposite a second exposed major surface and side surfaces extending between the first and second exposed major surfaces, the acoustic structural panel comprising a first protective layer comprising at least a portion of the first exposed major surface, a second protective layer comprising at least a portion of the second exposed surface, a core structure located between the first and second protective layers, the core structure comprising, a foam body; and a fibrous body, wherein the first major exposed surface of the acoustic structural panel comprises a plurality of apertures exposing the fibrous body.

A thermoplastic composite sheet for exterior cladding applications includes an outer layer with a thermoplastic resin composition reinforced with a high aspect ratio filler such that the outer layer has a coefficient of linear thermal expansion of no more than approximately 2.3310.sup.5 in/in/deg F., and a backing layer bonded to the outer layer, the backing layer defined by a foam material. The outer layer and the backing later define a body having a substantially planar outer surface.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a porous facing and to methods for making such panels. One aspect of the disclosure is an acoustic panel comprising a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The panel includes a coating layer directly disposed on the outward major surface of the base structure, the coating layer being formed of an open-cell foam. The coating layer has an exterior major surface opposing the outward major surface of the base structure. The coating layer is substantially scattering for light in the wavelength range of 380 nm to 780 nm, and has an absorption coefficient of less than 0.5 for acoustic frequencies in the range of 100 Hz to 10,000 Hz.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The polyurethane foam core has a density of 15-80 kg/m.sup.3. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article has a weight per unit area of 500-1000 g/m.sup.2 and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in according with SAE J949 at 23 C.
