description	trata-se de um método para produzir uma espuma de poliuretano semirrígida de baixa densidade de célula aberta adequada para uso geral como um material de isolamento térmico e/ou aplicações acústicas. o método compreende produzir uma espuma de poliuretano semirrígida de célula aberta retardadora de chama que tem uma densidade geral de 5 a 30 kg/m2 por meio da reação de (a) um poli-isocianato e (b) um poliol que tem um peso molecular de 100 a 10.000, na presença de (c) bis(bis(2-cloroetil)fosfato de 2,2-bis(clorometil)-trimetileno, (d) agente de expansão e (e) componentes adicionais opcionais. Disclosed is a method for producing an open cell low-density semi-rigid polyurethane foam suitable for general use as a thermal insulating material and/or acoustical applications. The method comprises producing a flame-retardant open-celled semi-rigid polyurethane foam having an overall density of 5 to 30 kg/m2 by reacting (a) a polyisocyanate and (b) a polyol having a molecular weight of 100 to 10,000, in the presence of (c) 2,2-bis(chloromethyl)-trimethylene bis(bis(2-chloroethyl)phosphate, (d) blowing agent, and (e) optional additional components.
