| description | The present invention relates to a sinter powder (SP) comprising 59.5% to 99.85% by weight of at least one thermoplastic polyurethane (A), 0.05% to 0.5% by weight of at least one flow agent (B), 0.1% to 5% by weight of at least one organic additive (C), 0% to 5% by weight of at least one further additive (D) and 0% to 30% by weight of at least one reinforcer (E), based in each case on the sum total of the percentages by weight (A), (B), (C), (D) and (E). The present invention further relates to a method of producing a shaped body by sintering the sinter powder (SP), to a shaped body obtainable by the method of the invention, and to the use of at least one flow agent (B) and at least one organic additive (C) in a sinter powder (SP) to improve the flowability and coalescence of the sinter powder (SP). The present invention further relates to the use of the sinter powder (SP) in a sintering method, and to a method of producing the sinter powder (SP). |
