Abstract:
The invention relates to expandable compositions containing a) a mixture of ai) thermoplastic polyurethane and aii) ethylene-propylene (EPM) rubbers and/or modified ethylene-propylene (EPM) rubbers, and b) at least one sponging agent.
Abstract:
The invention relates to a method for stabilising and securing rivers, slopes and embankments and constructions which can be at least partially displaced in water, such as support and construction elements by composite material made from mineral particles, preferably stones, in particular, gravel, and an epoxy resin.
Abstract:
The invention relates to a method for coating, gluing or connecting surfaces of mineral materials with a two-component plastic resin, selected from a hydrophobic polyurethane resin and a hydrophobic epoxy resin, by applying the plastic resin on the surface or connecting the surfaces of the mineral materials with the plastic resin and by leaving the plastic resin to harden. The invention is characterized in that the plastic resin contains 0.01 to 10 percent by weight of one or more hydroxy or alkoxy aminosilane compounds of general formula (I), wherein X independently of one another represents OH, CH 3 , O[CH 2 ] p CH 3 ; Y = [CH 2 ] t , [CH 2 ] r NH[CH 2 ] s ; R, R' H, [CH 2 ] t CH 3 ; t = 0 - 10; n = 1 - 3; p = 0 - 5; m = 4 - n; r, s independently of one another represent 1 - 10.
Abstract:
The invention relates to composite elements for furniture, preferably furniture doors and furniture bodies comprising (i) laminated or unlaminated materials made from wood, wooden boards or chipboards and/or wood-like materials, preferably made from wood or chipboard and (ii) thermoplastic polyurethane. The invention further relates to methods for production of said composite elements and particularly furniture bodies or doors comprising said composite elements. The invention particularly relates to integral hinges, preferably for furniture construction, for example for furniture bodies, drawers or door frames, in particular for furniture bodies made from thermoplastic polyurethanes.

Abstract:
The invention relates to a component which is at least partly made of a layer structure. The layer structure comprises the following layers: (a) an elastomer layer with a density of more than 800 g/L, and (b) a duromer layer containing at least 50 wt.% of a first polyurethane. The invention further relates to a method for producing such a component, having the following steps: (i) providing a negative mold, into which the individual layers of the layer structure are introduced, or a positive mold, onto which the individual layers of the layer structure are applied, (ii) producing the elastomer layer by means of a spraying process, (iii) producing the duromer layer by means of a spraying process, and (iv) removing the produced component, wherein step (ii) can be carried out before step (iii) or step (iii) can be carried out before step (ii).
Abstract:
The invention relates to a method for producing roads, paths and other surfaces for traffic. According to said method, a mixture containing crushed road surface material, mineral material and/or glass, a polymer reaction mixture and optionally other additives is produced, is applied to a foundation and is hardened. The invention also relates to roads, paths and other surfaces for traffic that are obtained according to a method of this type.
