Abstract:
The invention relates to molded bodies comprising a composition (Z1), wherein the composition contains at least one polymer having an elongation at break of > 30% and at least one porous metal-organic framework material, to methods for producing such molded bodies, and to the use of a composition (Z1), containing at least one polymer having an elongation at break of > 30% and at least one porous metal-organic framework material, to produce a film, a membrane, or a laminate having a water vapor permeability according to DIN 53122 at 38°C/90% relative humidity of greater than 1000 g/(m²*d), with respect to a film thickness of 10 µm.
Abstract:
The invention relates to a method for producing at least two-layered thermoplastic plates by means of thermal welding of at least one first thinner thermoplastic plate having a density (D1) and at least one second thinner thermoplastic plate having a density (D2), wherein the density (D1) of the first thinner thermoplastic plate is smaller than the density (D2) of the second thinner thermoplastic plate. In the method at least one first heating element and at least one second heating element are inserted between the two thinner thermoplastic plates, on planes which are offset relative to each other, wherein the surfaces of the thinner thermoplastic plates do not contact the surfaces of the heating elements. The first heating element transfers a quantity of energy (E1) to the surface of the first thinner thermoplastic plate and the second heating element transfers a quantity of energy (E2) to the surface of the second thinner thermoplastic plate, wherein the quantity of energy (E1) is smaller than the quantity of energy (E2).
Abstract:
The invention relates to a catching device for moving objects or persons, said device being based on thermoplastic polyurethane obtained by reacting at least one of each of the following starting materials: (a) diisocyanate, (b) compounds which are reactive towards isocyanate and which have a number-average molecular weight (Mw) between 0.500 x 10 3 g/mol and 10 x 10 3 g/mol, and (c) a chain-elongating agent which has a molecular weight between 50 g/mol and 499 g/mol, optionally: (d) using a catalyst, conventional auxiliaries, and/or (f) additives, wherein the catching device comprises a film or a net, which is made of the thermoplastic polyurethane, and retaining devices, between which the film or the net is stretched flat, and the thermoplastic polyurethane is transparent. The invention further relates to the use of thermoplastic polyurethane for producing catching devices and to a method for producing a catching device made of thermoplastic polyurethane.
Abstract:
The invention relates to a method for obtaining water for domestic use by the condensation of mist on the webs of an open-cell aminoplast-based foam and/or to a method for obtaining water for domestic use by the evaporation of water containing salt or impurities from the cells of an open-cell aminoplast-based foam and by the condensation of the evaporated water. The open-cell foam is produced from a melamine/formaldehyde condensation product with a molar ratio of melamine to formaldehyde ranging between 1:1 and 1:5.
Abstract:
The present invention relates to a process for recycling polyphasic mouldings (F1) comprising at least one foamed phase and at least one unfoamed phase produced by reaction injection moulding (RIM), wherein the moulding is first compressed, comminuted and heated and then processed in the plasticized state to a moulding (F2), the unfoamed phase comprising polyamide.
Abstract:
The invention relates to a method for producing fiber-reinforced, flat semi-finished products (3) on a polyamide matrix, comprising the following steps: (a) saturating textile structures (15) with a mixture containing molten lactam, catalyst and optionally activator, (b) cooling the saturated textile structures (25), (c) fabricating the fiber-reinforced, flat semi-finished product (3) from the cooled textile structures. The invention further relates to a method for producing a component from the fiber-reinforced, flat semi-finished product.
