PURPOSE: A pellet type flame retardant resin composition is provided to improve flame retardance, to improve processability of a polymer, and to have excellent resin application, excellent process treating performance, and coloring performance. CONSTITUTION: A pellet type flame retardant resin composition comprises one or more condensed mixtures selected from a group consisting of 1-80.0 wt% of pyrophosphate, 0.1-30 wt% of piperazine diphosphate, and 10-80 wt% of melamine polyphosphate. The flame retardant mixture additionally comprises 1 wt% or less of volatile material containing moisture. The pellet type flame retardant resin composition is obtained through heating treatment using pellet molded product and/or molded pellet which are obtained by heating the condensed mixture in a pellet press, an autoclave, or a extruder, etc at 25-300°C. A flame retardant plastic molding composition comprises the flame retardant mixture. |
