Fire retardant formulations

A fire-retarded styrene-containing polymer comprising fire-retardant formulation for injection-molding or extrusion, wherein said fire-retardant formulation comprises tris(2,4,6-tribromophenoxy)-s-triazine (FR-245), antimony trioxide and polytetrafluoroethylene (PTFE) and optionally carbon black, wherein the bromine concentration in said fire-retardant formulation is from about 9.0 to about 10.5 wt. % and the antimony trioxide concentration is equal to or less than 3.0 wt. %, while excluding tris(tribromoneopentyl)phosphate (FR-70) from said formulation.

A method for fire retarding a styrene-containing polymer, said method comprising incorporating into said polymer a fire-retardant formulation comprising tris(2,4,6-tribromophenoxy)-s-triazine (FR-245), antimony trioxide to a concentration equal to or less than 3.0 wt %, polytetrafluoroethylene (PTFE), optionally carbon black and optionally a brominated epoxy resin (BEO) or an endcapped brominated epoxy resin (MBEO), while excluding tris(tribromoneopentyl)phosphate (FR-70) from said formulation.
