Abstract
The main goal of this work was to evaluate the thermal insulation and sound absorptionproperties of open-cell rigid polyurethane foams synthesized with different contents of cookingoil-based polyol. The content of the applied bio-polyol as well as flame retardant (triethyl phosphate)in the foam formulation had a significant influence on the cellular structures of the materials.The open-cell polyurethane foams were characterized by apparent densities in the range 16–30 kg/m3.The sound absorption coefficients of the polyurethanes with various contents of bio-polyol weredetermined using the standing wave method (Kundt’s tube) in the frequency range of 100–6300 Hz.The effect of the content of the bio-polyol and flame retardant on the coefficient of thermal conductivity(at average temperatures of 0, 10 and 20◦C) as well as the compressive strength (at 20 and−10◦C)was analyzed. Different trends were observed in terms of the thermal insulation properties and soundabsorption ability of the open-cell polyurethanes due to the addition of bio-polyol. In conclusion, it isnecessary to use systems containing both petrochemical and bio-based raw materials.
