摘要： The invention relates to a method for producing a rigid polyurethane or polyisocyanurate foam, by converting at least one polyisocyanate, and a polyol composition (PZ), wherein the polyol composition (PZ) contains at least one compound with at least two hydrogen atoms, which are reactive towards isocyanate groups, and at least one compound (I) selected from the group consisting of dicarboxylic acid diesters of dicarboxylic acids with 2 to 18 C atoms and tricarboxylic acid triesters of tricarboxylic acids with 3 to 18 C atoms. At least one propellant is used during the conversion process. The invention further relates to rigid polyurethane or polyisocyanurate foams which are obtained or can be obtained using such a method and to a polyol composition (PZ) at least containing a compound with at least two hydrogen atoms, which are reactive towards isocyanate groups, and at least one compound (I) selected from the group consisting of dicarboxylic acid diesters of dicarboxylic acids with 2 to 18 C atoms and tricarboxylic acid triesters of tricarboxylic acids with 3 to 18 C atoms. The invention also relates to the use of such a polyol composition (PZ) in the production of rigid polyurethane or polyisocyanurate foams and to the use of a rigid polyurethane or polyisocyanurate foam according to the invention as insulating materials or for producing insulating materials, preferably insulating panels, sandwich elements, hot water tanks, boilers, cooling equipment, insulating foams, cooling devices, or freezing devices.

摘要： The invention relates to a method for producing polyurethane rigid foams by reacting a) at least one organic polyisocyanate with b) at least one polyol component in the presence of a blowing-agent mixture containing water and halogenated alkenes, wherein the amount of water is at least 1.40 mol/kg polyol component b) and the amount of halogenated alkene is at most 2.00 mol/kg polyol component b), and to the use of such a blowing-agent mixture to produce corresponding polyurethane rigid foams and to increase the adhesion and to reduce the thermal conductivity of corresponding polyurethane rigid foams. The invention further relates to a polyurethane rigid foam that can be produced by the method according to the invention.
