Abstract: The present application relates to citric acid-modified polypropylene glycols which are represented by Formula (1) or, as well as compositions comprising such compounds. The polypropylene glycol-based compounds of the invention are useful as additives and in particular as emulsifying agents in e.g. cooling lubricants, as release agents, as well as additives for cosmetic products.

Abstract: The present invention relates to a composite material comprising at least one thermoplastic polymer and a particulate inorganic material and its use in additive manufacturing methods.

Abstract: The invention relates to a filter device comprising an inlet and an outlet. An adsorption section is positioned along the flow path between and inlet section and an outlet section, and is filled with glass beads of a predetermined nominal diameter as well as an absorption granulate mixed with said glass beads. The inlet section and outlet section are filled with glass beads with a nominal diameter preferably at least as big as the nominal diameter of the glass beads of said adsorption section.

Abstract: The invention relates to a plastic mixture with electromagnetic shielding characteristics based on a matrix with a content of ferroelectrics and electrically conductive and/or ferromagnetic fillers, which is characterized in that the ferroelectric component has a Curie point or a phase transition range from the ferroelectric into the paraelectric phase covering the Curie point and which is in the range of the use temperature of -40.degree. to +98.degree. C. of the electromagnetic shielding material and, based on the electromagnetic material volume, is present in a quantity of 1 to 20 vol. %, whilst the electrically conductive or ferromagnetic fillers are present in quantitites of 5 to 15 vol. %, the ferroelectric component preferably being an organic compound selected from the group consisting of semi carbadize-hydrochloride, 3,4-dihydroxy-3-cyclobutene-1,2-dione and triglycine sulphate and the inorganic compound is from the group consisting of barium-strontium titanate and antimony iodide sulphide.
