The invention relates to a method for determining polymeric product properties (), wherein a prediction model () is provided for calculating polymeric product properties () based on production parameters on a computer system, which production parameters comprise formulation portions () specifying raw material portions for polymeric production and comprise processing parameters () specifying process properties during polymeric production, wherein user input is provided to the computer system, which user input comprises user production parameters () specifying a set of production parameters, user product parameters () specifying polymeric product properties and a proximity metric for quantifying conformity with the user product parameters (), wherein the computer system applies the user production parameters () to the prediction model () to calculate resultant product properties (), wherein the computer system applies the proximity metric to the resultant product properties () with respect to the user product parameters () to determine at least one proximity value indicating a match between the user product parameters () and the resultant product properties (). The invention also relates to a corresponding computer system for determining polymeric product properties.

The invention relates to a method for the production of foamed areal polyurethane(PUR)/polyisocyanurate(PIR) moldings, where a polyurethane/polyisocyanurate reaction mixture is injected into a mold that is under elevated pressure and then a depressurization takes place, and the foaming process is thus induced, and after the reaction the molding is demolded, and to a mold for carrying out the method.
