| titleOfInvention | Method for producing polyurethane and polyisocyanurate rigid foam |
| abstract | The invention relates to a method for producing polyurethane or polyisocyanurate rigid foam by reacting polyisocyanates a) with compounds comprising at least two hydrogen atoms reactive with isocyanate groups b) in the absence of foaming agents. Said method is characterised in that c) the polyisocyanates used are a) prepolymers containing isocyanate groups and having an NCO content of between 25 and 31 wt. % in relation to the weight of the prepolymer, said prepolymers being produced by reacting ai) mixtures of monomer and polymer diphenylmethane diisocyanate with at least one compound comprising more than one hydrogen atom aii) reactive with isocyanate groups, and the compounds comprising at least two hydrogen atoms reactive with isocyanate groups b) contain at least one polyester alcohol bi) containing at least one hydrophobic initial constituent. |
