Abstract (en)
[origin: WO2022258434A1] 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.
