  • METHOD FOR PRODUCING A RIGID POLYURETHANE FOAM
    Publication number: 20180186924
    Abstract: The present invention relates to a process for the production of a rigid polyurethane foam or rigid polyisocyanurate foam, comprising the reaction of at least one polyisocyanate and of a polyol composition (PZ), where the polyol composition (PZ) comprises at least one compound having at least two hydrogen atoms reactive toward isocyanate groups and at least one compound (I) selected from the group consisting of dicarboxylic diesters of dicarboxylic acids having from 2 to 18 C atoms and tricarboxylic triesters of tricarboxylic acids having from 3 to 18 C atoms, where at least one blowing agent is used during the reaction.

  • HFO/water-blown rigid foam systems
    Patent number: 9896558
    Abstract: 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.
