Abstract: A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.

Abstract: A method for producing a shaped body, containing: producing the shaped body from a composition by a powder-based layer construction process, wherein the composition contains a thermoplastic polyurethane, obtained by reacting a polyisocyanate composition and a polyol composition, the thermoplastic polyurethane is solid at least in a temperature region below 50° C. and has end groups selected from the group consisting of first end groups and second end groups, wherein the first end groups are optionally eliminated at a first temperature, and the second end groups are optionally eliminated at a second temperature, to form reactive groups on the thermoplastic polyurethane that optionally enter into a reaction with functional groups of the thermoplastic polyurethane or functional groups of a further component of the composition, and wherein the first temperature and the second temperature are each greater than or equal to 60° C.

Abstract: The present invention is directed to a polyisocyanate polyaddition product, obtained or obtainable according to a process containing reacting at least a polyisocyanate composition (C-I) comprising at least one polyisocyanate; and a composition (C-II) comprising at least one compound (C-A) having at least two functional groups which are reactive towards isocyanate groups, wherein the compound (C-A) has a molecular weight of 500 g/mol or more and comprises polycyclic aromatic moieties. The present invention is further directed to a process for preparing said polyisocyanate polyaddition product and the use thereof in a cable, conveyor belt, roller, seal for gasket or railway pad.

Abstract: The present invention relates to a process for producing a polyurethane, comprising the reaction of a polyol composition (PZ) comprising a polyol (P1) with a polyisocyanate composition (PIZ-1) comprising a polyisocyanate (I1) to obtain a hydroxyl-terminated prepolymer (PP1) and the reaction of the prepolymer (PP1) obtained with a polyisocyanate composition (PIZ-2) comprising a polyisocyanate (I2) and at least one chain extender (K1) to obtain a polyurethane (PU1), wherein the molar ratio of the OH groups in the components of the polyol composition (PZ) to the isocyanate groups in the components of the polyisocyanate composition (PIZ-1) in the reaction in step (i) is in the range from 1.3:1 to 10:1. The present invention further relates to polyurethanes obtainable or obtained by such a process, and to the use of the polyurethanes for production of shaped bodies, adhesives, coatings, hoses, films, nonwoven articles or fibers.

Abstract: The present invention relates to the use of a composition for stabilizing a geological formation in oil fields, gas fields, water pumping fields, mining or tunnel constructions. The composition has a hardening temperature in the range from about 40° C. to about 120° C. and can therefore be used to stabilize a geological formation in oil fields, gas fields, water pumping fields as well as in mining or tunnel constructions.
