Zusammenfassung:	A thermoset foam comprises from 0.2 to 4.0 wt. % of at least one aliphatic brominated polyether polyol, from 2.0 to 7.0 wt. % of at least one aromatic brominated polyester polyol, and from 2.0 to 7.5 wt. % of at least one flame retardant comprising organo-phosphate, organo-phosphonate, or organo-phosphite, wherein the ratio of the amount of aliphatic bromine expressed as a percentage of total bromine to the amount of aromatic bromine expressed as a percentage of total bromine is from 10:90 to 50: 50. Une mousse thermodurcie comprend de 0,2 à 4,0 % en poids d'au moins un polyol de polyéther bromé aliphatique, de 2,0 à 7,0 % en poids d'au moins un polyester polyol bromé aromatique, et de 2,0 à 7,5 % en poids d'au moins un retardateur de flamme comprenant un organo-phosphate, organo-phosphonate, ou organo-phosphite, le rapport de la quantité de brome aliphatique exprimé en pourcentage de brome total à la quantité de brome aromatique exprimé en pourcentage de brome total étant de 10 : 90 à 50 : 50.
