The invention refers to a method for producing expanded polymer pellets, which comprises the following steps: melting a polymer comprising a polyamide; adding at least one blowing agent; expanding the melt through at least one die for producing an expanded polymer; and pelletizing the expanded polymer. The invention further concerns polymer pellets produced with the method as well as their use, e.g. for the production of cushioning elements for sports apparel, such as for producing soles or parts of soles of sports shoes. A further aspect of the invention concerns a method for the manufacture of molded components, comprising loading pellets of an expanded polymer material into a mold, and connecting the pellets by providing heat energy, wherein the expanded polymer material of the pellets or beads comprises a chain extender. The molded components may be used in broad ranges of application.

The present invention relates to an expandable polymeric composition that comprises: a) from 60% to 88% by weight of a vinyl aromatic polymer and/or copolymer, calculated respect to (a)+(b); b) from 12% to 40% by weight of a block copolymer, containing at least one vinyl aromatic polymer and/or copolymer and at least one hydrogenated diene polymer, calculated respect to (a)+(b); c) from 3 parts to 10 parts by weight of a blowing agent, calculated on 100 parts of (a)+(b).

A method of manufacturing a flexible intrinsically antimicrobial absorbent porosic composite controlling for an effective pore size using removable pore-forming substances and physically incorporated, non-leaching antimicrobials. A flexible intrinsically antimicrobial absorbent porosic composite controlled for an effective pore size composited physically incorporated, high-surface area, non-leaching antimicrobials, optionally in which the physically incorporated non-leaching antimicrobial exposes nanopillars on its surface to enhance antimicrobial activity. A kit that enhances the effectiveness of the intrinsically antimicrobial absorbent porosic composite by storing the composite within an antimicrobial container.

A method of reducing aldehyde concentration in a vehicle cabin air, the method includes applying a solution comprising aldehyde scavenger(s) onto an outer surface of a foam article located or to be located within a vehicle cabin to form a top layer of the article such that aldehyde species are trapped within the article and prevented from being released into the cabin air.

The invention relates to an acoustic phase mask, the phase mask having a variation in the acoustic index n, characterized in that the phase mask comprises a body comprising: at least one matrix formed from a deformable solid material, having a shear modulus of less than 10 MPa, and pores formed in the matrix, the pores being mostly filled with gas, the deformable solid material extending between the pores, the body having a porosity φ less than or equal to 50%, and a controlled porosity φ gradient resulting in a variation of the acoustic index n spatially in the body.
