Powdered composition of polymer and ammonium polyphosphate-containing flameproofing agent, method for producing the same, and molded product produced from this 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.
