Process for flameproofing plastics

摘要

A process for flameproofing plastics comprising incorporating in the plastic a homogeneous granulate containing pulverulent red phosphorus with a particle size of up to about 100 microns and a binder; the granulate is more particularly comprised of a blend of 10-97% BY WEIGHT OF RED PHOSPHORUS, 3-50% BY WEIGHT OF A BINDER MELTING BETWEEN ABOUT 30 DEG AND 180 DEG C. and being selected from waxes and/or waxy substances and/or metal soaps, and up to 87% by weight of addends promoting the flameproofing efficiency of the granulate, inhibiting the evolution of gaseous phosphines upon the incorporation of the granulate with the plastics, or being suitable fillers.
