Abstract: It is provided a refrigerator appliance (1) having at least one internal liner (2), in particular a cabinet liner or a door liner, defining an inner compartment (3) and made of a polypropylene-based material comprising a propylene-ethylene copolymer having a main polypropylene chain with ethylene units arranged along the polypropylene chain; and at least one lamellar or fibrolamellar filler. The material makes it possible to effectively manufacture the liner (2) by thermoforming.

Abstract: A refrigerator appliance having at least one internal liner, in particular a cabinet liner or a door liner, defining an inner compartment and made of a blend material comprising a mixture of a propylene-ethylene copolymer and a polymer selected in the group consisting of PE and EVA.

Abstract: A method for manufacturing a liner, in particular for the cabinet of a refrigerator, allowing to leave out a deep thermoforming step. The method includes extruding a sheet, trimming the sheet, folding the sheet and joining adjacent edges of the sheet.

Abstract: An insulated component (1) of a household appliance, in particular of a dishwasher, comprising a substrate (10) and an insulation structure (12) applied onto a surface (13) of the substrate (10); wherein the insulation structure (12) comprises one or more layers (14) made of one or more sprayable filled polyurethane materials, wherein said one or more layers (14) comprise a layer (14a, 14d) made of elastomeric polyurethane material applied directly onto the surface (13) of the component (1) and having the following properties: a specific density comprised between 1 and 3 g/cm3; a tan delta at 20° C. and at 100-300 Hz comprised between about 0.4 and 1.6; and a tan delta at 60° C. and at 100-300 Hz comprised between about 0.5 and 2.2.

Abstract: A process for preparing formed articles made of polyurethane foams, which comprises reacting at least a polyisocyanate with at least a compound containing end activated hydrogens in the presence of an expanding medium, selected from at least a hydrofluoroalkane and/or perfluoroalkane, and of a product, containing at least a structural unit of the aminic type, chemically bound or present in free form in one of the two polyurethane reagents, said expanding medium being dissolved in said one of the two polyurethane reagents.
