    Abstract: A foamed, opacifying element has a substrate with opposing planar surfaces and a foamed opacifying layer disposed on one opposing surface. The foamed opacifying layer contains (a) 0.1-80 weight % of nonporous polymeric particles; (b′) 10-80 weight % of a matrix material derived from a (b) binder material having a glass transition temperature of less than 40° C.; (c) 0.0001-50 weight % of certain additives; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the (c) additives. Foamable and foamed aqueous compositions can be used to provide these foamed, opacifying elements for use as light-blocking window shades, curtains, or other materials. These light-blocking articles can also have a printable outer surface that accepts ink for making printed images that are not observable from the opposite surface.

    Abstract: A formed body with a cavity structure for the sound and/or heat insulation of buildings. The formed body has a cavity structure and has pre-foamed polystyrene particles compressed in a mould or on a conveyor belt system under the influence of pressure and/or heat. The formed body has a communicating cavity volume and the communicating cavity volume has a volume fraction that amounts to 5 to 30 vol. %, preferably 10 to 25 vol. %, particularly 15 to 20 vol. %, referred to the total volume of the formed body, and comprising at least part of the pre-foamed polystyrene particles firmly enclosed in a cured organic or inorganic binder that is used for coating at least part of the polystyrene particles prior to their compression in a mould or on a conveyor belt system.
