A method of manufacturing an embossed hydrophobic covering element for construction or decoration for protecting the surface from humidity or inclement weather. This method includes preparing a mixture of water and at least one organic material in a tank in which the organic material is insoluble in water, stirring the mixture so as to disperse the organic material in suspension in water, molding the prepared and stored mixture by immersing a forming mold under vacuum inside the tank in order to form a molded element, drying and densifying the molded element under vacuum so as to obtained a dried and densified element, and fully impregnating the dried and densified element in the binder so as to form the hydrophobic covering element. The binder is of an organic material. The organic material originates from a sustainably renewable resource.

The present invention relates to high-voltage components, especially for electromobility, comprising polymer compositions based on at least one polyester and 10,10′-oxybis-12H-phthaloperin-12-one, and to the use of 10,10′-oxybis-12H-phthaloperin-12-one for production of polyester-based products, with the proviso of a color difference ΔE<20 from the L*a*b* coordinates of a color number beginning with “2” in the RAL color chart, and to the use of 10,10′-oxybis-12H-phthaloperin-12-one for marking of polyester-based products as high-voltage components.

A vehicle headrest includes an electro-acoustic transducer and an acoustic enclosure that supports the electro-acoustic transducer. A unitary foam member is coupled to the acoustic enclosure. The foam member has regions of contrasting firmness including a first region having a first firmness and a second region having a second firmness that is greater than the first firmness. The second region defines a speaker grille that is configured to overlie the electro-acoustic transducer.

A foamable, insulating-layer-forming multi-component composition contains alkoxysilane-functional polymer, insulating-layer-forming fire-protection additive, blowing-agent mixture, cross-linking agent, and a flame-protection agent that is miscible in water or another compound that is miscible in water. The individual ingredients of the blowing-agent mixture are separated from one another to ensure inhibition of reaction prior to use of the composition, and the cross-linking agent is separated from the alkoxysilane-functional polymer to ensure inhibition of reaction prior to use of the composition. The foamable, insulating-layer-forming multi-component composition can be used as a foam-in-place foam or for production of molded blocks.
