POWDERY COMPOSITION OF A POLYMER AND A FLAMEPROOFING AGENT CONTAINING AMMONIUM POLYPHOSPHATE, METHOD FOR THE PRODUCTION THEREOF, AND MOULDED BODY PRODUCED FROM SAID POWDER

摘要

Powder composition for use in the layerwise buildup of three-dimensional articles in which portions of the powder are selectively bonded together comprises a polymer and an ammonium polyphosphate flame retardant and has a particle size of 150 mu m or less. An independent claim is also included for a shaped product produced by layerwise buildup of three-dimensional articles in which portions of a powder are selectively bonded together, comprising a polymer and an ammonium polyphosphate flame retardant.
