Abstract
Granular flame retardant agents are disclosed which incorporate halogenated organic flame-retardant compounds, without any binders. The granular agents may further contain desired additives and organic or inorganic flame-retardant synergistic materials. The granular agents are dust-free and are usefully employed in a method for imparting flame-retardant properties to flammable plastic materials. A process for the preparation of the granular flame retardant agents of the invention by cold compaction is also described.
