Abstract
The invention provides a process for production of polyurethane systems by reacting at least one polyol component with at least one isocyanate component in the presence of one or more catalysts for the isocyanate-polyol and/or isocyanate-water reactions and/or the trimerization of isocyanate, wherein said reacting is carried out in the presence of carrier material and polyamine P.
Claims20
The process for production of polyurethane systems by reacting a polyol component with an isocyanate component in the presence of one or more catalysts for the isocyanate-polyol and/or isocyanate-water reactions and/or the trimerization of isocyanate, wherein said reacting is carried out in the presence of a carrier material and polyamine P.
A process for reducing aldehyde total emission from polyurethane systems, by admixture to the polyurethane system, of carrier material and polyamine P, in particular as recited in any of the preceding claims, in an amount of 0.001 to 10 wt %, based on the overall weight of the polyurethane system, wherein the admixture may take place before and/or during the production of the polyurethane system.
A process for reducing aldehyde total emission, in particular aldehyde emissions comprising formaldehyde, acetaldehyde, acrolein and benzaldehyde, from polyurethane foam systems, by admixture to the polyurethane foam system, of carrier material and polyamine P, in an amount of 0.01 to 5 wt %, based on the overall weight of the polyurethane foam system, wherein the admixture may take place before and/or during the production of the polyurethane foam system.
