Also provided is a zipper pouch made by that process.

The present invention relates to high-voltage components, in particular for electromobility, containing polymer compositions based on at least one polyamide and 10,10-oxybis-12H-phthaloperin-12-one, and to the use of 10,10-oxybis-12H-phthaloperin-12-one for marking polyamide-based articles of manufacture as high-voltage components.

Slider (1) for a car seat support which can be locked in different positions along a sliding direction (25), to be mounted in a metal rail (2), wherein the slider (1) has an extended base portion (3) and an extended upper portion (4). The base portion (3) and the upper portion (4) are connected by a constricted portion (13). The base portion (3) has two lateral guide portions (5,5) with guide protrusions (6,6) pointing upward in the direction of the upper portion (4) and forming, with the constricted portion (13), a groove (12) on each side. The slider may (1) essentially consist of fibre reinforced polyamide.

Polymer compositions that are usefully employed in high-voltage components, in particular for electromobility, are based on at least one polyamide and 10,10-oxybis-12H-phthaloperin-12-one, and to the use of 10,10-oxybis-12H-phthaloperin-12-one for marking polyamide-based articles of manufacture as high-voltage components.

The invention relates to a recycled, thermally stable polystyrene composition P, comprising a recycled polystyrene composition A, which comprises at least one polystyrene A-1 that is prepared by a thermally initiated and/or 1,1-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane initiated radical polymerization, and at least one sterically hindered phenolic antioxidant as component B. The invention also relates to a process for providing superior thermal stability in the mechanical recycling of polystyrene. Further, a recycled, thermally stable polystyrene composition P, a process for preparing the recycled, thermally stable polystyrene composition P and the use of the recycled, thermally stable polystyrene composition P for preparing molded articles are described.

A method and material for 3D printing objects containing heat-sensitive molecules are disclosed. The composition consists of a water-saturated, polar thermoplastic polymer, such as highly hydrolyzed polyvinyl alcohol (PVA), into which functional moleculesproteins, peptides, pharmaceuticals, fragrances, or living cellsare dispersed. The polymer is first hydrated to form a gel, extruded and cut into pellets, then partially dried through a multi-stage dehydration process that leaves a moisture-rich core and a dry outer shell. During extrusion at typical FDM nozzle temperatures (200 C.), entrapped water within the material vaporizes at 100 C., providing in situ evaporative cooling and maintaining the temperature of the functional molecules below their degradation point. The process enables additive manufacturing of structurally sound objects that preserve the activity of heat-sensitive additives, opening new applications for 3D-printed consumables, pharmaceuticals, and bio-functional components.

Provided is a composition described below as an EVOH resin composition having an increased thermal decomposition temperature at the time of melt-molding and excellent thermal stability. An ethylene-vinyl alcohol copolymer composition containing an ethylene-vinyl alcohol copolymer and a titanium compound, wherein the ethylene-vinyl alcohol copolymer has a saponification degree of more than 91 mol % and 99.5 mol % or less, and a content of the titanium compound in terms of metal is 0.001 ppm or more and less than 5 ppm per mass of the ethylene-vinyl alcohol copolymer composition.
