Coarse flame retardant

Abstract

A mixture is described that includes at least one polymer-based material in powder form and at least one halogen-free flame retardant in powder form. The flame retardant in powder form has a particle size distribution with a d50 in the region of 20 to 80 μm, preferably of at least 30 and/or at most 60 μm, and a d10 of greater than 10 μm, preferably greater than 15 μm, more preferably greater than 20 μm. Further disclosed is a method for producing such a mixture, a mixture obtainable by the method, the use of such a mixture as a building material for the additive manufacturing of a three-dimensional object, a three-dimensional object produced by solidifying this mixture, as well as a method and a system for producing such a three-dimensional object.
