Piro - retardant compositions with a Polymer and a Concentrated Additive piro - retardant and Process for Increasing the yield rate of polimerodel Extruder.

摘要

They Reveal a composite flame retardant substance consists of coated particles, and these particles have a Core containing phosphate melamine POLYPHOSPHATE, melamineMelamine PYROPHOSPHATE, or mixtures of these being the core, and has at least a recubrimientoque includes a organosilano, an ester, a polyol, a Dianhidrido, a dicarboxylic acid,Melamine formaldehyde or mixtures thereof; a composicionpolimu00e9rica containing Said pirroretardante; a Polymer composition containing a Polymer composition which contains a pirroretardante;Ne unpirroretardante consists of phosphate of melamine, melamine POLYPHOSPHATE, melamine PYROPHOSPHATE or mixtures thereof and dicarboxylic acid, Dianhidrido,Or mixtures thereof; and a process for the preparation of such polymeric compositions by increasing the throughput of the Extruder.
