The present invention relates to a process for producing a thermoplastic polyurethane reacting at least one thermoplastic polyurethane (TPU-1) or a polyurethane mixture comprising a thermoplastic polyurethane (TPU-1) with at least one compound (V1) comprising two hydroxyl groups to obtain a mixture (G-a) comprising a thermoplastic polyurethane (TPU-2) and the reaction of the mixture (G-a) with a mixture (G-b) comprising an isocyanate composition (ZI) comprising at least one diisocyanate and optionally and a polyol composition (ZP) comprising at least one polyol (P2) to obtain a thermoplastic polyurethane (TPU target), wherein the proportion of the employed components (ZI) and (ZP) is matched to the hard segment content of the employed thermoplastic polyurethane (TPU-1), (V1) and the hard segment content of the thermoplastic polyurethane (TPU target). The invention further relates to a thermoplastic polyurethane obtained or obtainable by such a process and to the use thereof for producing extruded, injection molded and pressed articles as well as foams, cable sheathings, hoses, profiles, drive belts, fibers, nonwovens, films, moldings, soles, sporting goods, shoes, plugs, housings, damping elements for the electricals industry, automotive industry, mechanical engineering, 3D printing, medicine and consumer goods.

Thermoplastic polyurethane from recycled raw materials

Multi-layer composite materials comprising a plastic or metal foil, corresponding method of production and use thereof Multilayered composite materials comprising as components:

Multi-layer composite materials comprising a plastic or metal foil, corresponding method of production and use thereof

Multi-layer composite materials comprising a layer of cellulosic material, optionally at least one bonding layer and a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer; a corresponding method of production; and use thereof such as in packaging and decorative materials. An object of the multi-layer composite materials is the processing of cellulosic substrates such that they have an appealing visual appearance and pleasant haptics and are impervious to fingerprints, sweat marks and moisture.

Multi-layer composite materials comprising a cellulose-containing layer, corresponding method of production and use thereof

Method for continuously producing multi-layered composite bodies A process for continuous production of multilayered composite articles which comprise comprises using a mold to produce polyurethane layer (C) and fixing said polyurethane layer (C) on said backing material (A) with the aid of a material which converts to said bonding layer (B), the mold having a temperature in the range from 80 to 170&#xb0; C and a heat capacity in the range from 100 to 20 000 J/K&#xb7;m.

Method for continuously producing multi-layered composite bodies

Condensates of polyalkylenepolyamines, their preparation and their use

A process for chemically degrading cured amino resins comprises reacting cured amino resins, which may contain fillers, with a primary and/or secondary amine at from 40.degree. to 250.degree. C.

Chemical degradation of cured amino resins

Cured aminoplast resins are recycled by a process in which said resins, which may contain fillers, are treated with an aqueous sulfite, hydrogen sulfite or disulfite solution and the resulting low molecular weight degradation products are used in chemical processes. The resulting low molecular weight degradation products of cured aminoplast resins are used for coating moldings, for tanning leather and skins and for the production of moldings which contain cured aminoplast resins or consist thereof.
