Rigid polyurethane-polyisocyanurate foams (PUR-PIR) containing from 2.5% to 20% w/w of fillers (talc, aluminum hydroxide, chalk, starch and borax) were the subject of our studies; a reference sample was PUR-PIR foam with no filler added. Apparent density, compressive strength, brittleness, content o...
