Patent ID: 8663509

Claim:
A UL-94 V-0 fire retarded styrenic polymer consisting of a mixture of styrenic polymer, and a fire retardant formulation consisting of either: (A) (i) tris(2,4,6-tribromophenoxy)-s-triazine (FR-245); (ii) antimony trioxide; (iii) polytetrafluoroethylene (PTFE); (iv) carbon black; and (v) a brominated epoxy resin (BEO) or an endcapped brominated epoxy resin (MBEO); (B) (i) tris(2,4,6-tribromophenoxy)-s-triazine (FR-245); (ii) antimony trioxide; (iii) polytetrafluoroethylene (PTFE); and (iv) a brominated epoxy resin (BEO) or an endcapped brominated epoxy resin (MBEO); (C) (i) tris(2,4,6-tribromophenoxy)-s-triazine (FR-245); (ii) antimony trioxide; (iii) polytetrafluoroethylene (PTFE); and (iv) carbon black; or (D) (i) tris(2,4,6-tribromophenoxy)-s-triazine (FR-245); (ii) antimony trioxide; and (iii) polytetrafluoroethylene (PTFE); wherein the bromine concentration in said fire retarded styrenic polymer is from about 9.0 to about 10.5 wt. %, the antimony trioxide concentration is equal to or less than 3.0 wt. %, and the PTFE concentration is from about 0.03 to 0.2 wt %.
