A rye slop (92.2% of H2O and 7.8% of dry mass), a by-product in the process of making high wines, were added as a filler (5-30 % by weight in relation to total weight of polyisocyanurate and oligomerol) to PUR-PIR foam composition (Table 3). Apparent density, compressive strength, friability, oxygen index, combustion residue, dimensional stability at 120°C, softening point and TGA thermograms were determined for the seven foams prepared (Figs. 1-5). Foams characterized by reduced brittleness, slightly reduced oxygen index, retention and softening temperature and slightly increased compressive strength in relation to the standard foam (with no rye slop added) were obtained when rye slops were added in amounts from 5% to 30% by weight. IR spectra confirmed the presence of bands characteristic for isocyanurate and urethane groups.
