Nowy poliol boroorganiczny do produkcji sztywnych pianek poliuretanowo-poliizocyjanurowych: Cz. II. OTRZYMYWANIE SZTYWNYCH PIANEK POLIURETANOWO- -POLIIZOCYJANUROWYCH Z ZASTOSOWANIEM NOWEGO POLIOLU BOROORGANICZNEGO

摘要: The conditions of polyurethane-polyisocyanurate (PUR-PIR) foams preparation with use new boroorganic compound as polyol are presented. is a product the reaction N,N'-di(methyleneoxy-3-hydroxypropylo)urea boric acid. results determination foaming process parameters well investigation foams' functional properties given. show that borate obtained component and simultaneously fire retardant in production PUR-PIR very beneficial. rigid less brittle, better compression strength higher content close cell much lower flammability comparison control sample. described improves polymers so could be effectively foams.
