ABSTRACT:
The present invention provides a new and improved flame retardant polypropylene composition that exhibits substantially no bloom and plate-out during processing and use. In a preferred embodiment the composition comprises a homopolymer or copolymer of polypropylene, a styrene butadiene compatibilizer, a bromine and phosphorus containing flame retardant additive and a metallocene ethylene copolymer. In addition to displaying excellent color development characteristics, the composition of the present invention displays excellent physical properties and a UL94 rating of V-2.
