Abstract: A powdery composition contains at least one polyamide (PA) powder and is characterized in that the PA powder comprises a first polyamide (A) selected from the group consisting of PA5.9, PA5.10, PA5.11, PA5.12, PA5.13, PA5.14, PA6, PA6.66, PA6.9, PA6.10, PA10.9, PA10.10, PA10.12, PA10.13, PA12.9, copolymers and mixtures thereof, and the PA powder satisfies the following parameters: a melting point in the range of 180 to 240° C., a melt flow index of 400 cm3/10 min or less, measured at a temperature from 50 to 55° C. above the melting point, a melt flow index of 325 cm3/10 min or less, measured at a temperature from 30 to 35° C. above the melting point, and a melt flow index of 250 cm3/10 min or less, measured at a temperature from 10 to 15° C. above the melting point, each time measured at a test load of 5 kg. Additionally, the pulverulent composition has an elongation at break of at least 5.0% after sintering in a dry, untreated condition.

Abstract: A pulverulent composition contains at least one polyamide (PA) powder and is characterized in that the PA powder satisfies the following parameters: a melting point in the range of 240 to 320° C., a melt flow index of 700 cm3/10 min or less, measured at a temperature of 30 to 35° C. above the melting point, and a melt flow index of 300 cm3/10 min or less, measured at a temperature of 10 to 15° C. above the melting point, each time measured at a test load of 5 kg. Additionally, the pulverulent composition has an elongation at break of at least 2.0% after sintering. The invention also relates to a molding that consists of such a pulverulent composition, a use of the pulverulent composition and a process for producing a molding.
