The invention relates to a flameproof polyurethane material (PU) consisting of a plurality of reactive polyol elements (S) and a plurality of reactive diisocyanate elements (H) and at least one reactive diamine or diol element operating as a chain extender (EXT) of the polyurethane (PU). A chain extender at least of the polyurethane material comprises a phosphoriferous oligomer element (R2) of a predefined length (1) having a value within a dispersion interval which is also predefined. The invention further relates to the polyurethanes (PU) produced by the implementation of said method. 本发明涉及耐火聚氨酯材料(PU)，由多种反应性多元醇成分(S)和多种反应性二异氰酸酯成分(H)以及用作聚氨酯(PU)的增链剂(EXT)的至少种反应性二胺或二醇成分组成。至少聚氨酯材料中的增链剂包含预定长度(l)的含磷低聚物成分(R2)，该预定长度具有也是预定的分散区间内的值。本发明进步涉及通过实施所述方法生产的聚氨酯(PU)。
