The present invention relates to a process for producing rigid polyurethane foams by reaction of a) at least one organic polyisocyanate with b) at least one polyol component in the presence of a blowing agent mixture comprising water and halogenated alkenes, wherein the amount of water is at least 1.40 mol/kg of polyol component b) and the amount of halogenated alkene is at most 2.00 mol/kg of polyol component b), and also to the use of such a blowing agent mixture for producing corresponding rigid polyurethane foams and for increasing the adherence and reducing the thermal conductivity of corresponding rigid polyurethane foams. The present invention further relates to a rigid polyurethane foam obtainable by the process of the present invention.

HFO/water-blown rigid foam systems

The present invention relates to a continuous process for producing a profile comprising at least one core made of a polyurethane foam or a mixture comprising a polyurethane foam, at least one jacket made of at least one thermoplastic material, and optionally at least one foil between core and jacket, to a profile produced via said process, to the use of this profile for producing windowframes, doorframes, or in the fitting-out of interiors, or in apparatuses in which, during operation, temperature differences arise between interior space and exterior space, and also to an apparatus for carrying out the process of the invention.

Extruded plastics profiles comprising continuously introduced insulation elements

The present invention relates to a dynamically evacuable, electrically operated device comprising a coherently evacuable region and a temperature-controllable useful region, which is thermally insulated from the ambient temperature by the coherently evacuable region, and also a means for actively maintaining a vacuum, such that the pressure in the coherently evacuable region of the device is constantly within a defined pressure range, said coherently evacuable region making up at least 20% by volume of the total volume which is occupied by a porous and/or cellular insulating material in the device, and said coherently evacuable region comprising at least one organic aerogel and/or organic xerogel.
