Abstract:
1. A flame-retardant composition comprising: (a) a copolymer comprising at least about 50 wt. % of propylene-derived units, and about 5-35 wt. % of units derived from at least one of ethylene or a C (b) 25-35 wt % of a flame retardant, wherein the flame retardant comprises a halogenated hydrocarbon, a metal oxide, and a char-forming material and wherein the metal oxide is present in an amount of about 2-5 times the amount of the halogenated compound by weight, wherein the halogenated hydrocarbon is present in an amount of about 2.0-7.0 wt. % of the composition; wherein the composition satisfies the requirements of UL94 with a V2 rating; and wherein the composition has a Shore A hardness in the range of from about 60.0-95.0, an Ultimate Tensile Strength of at least about 5 mPa, and an Ultimate Elongation of at least about 600%.
