Claim:
1. A thermoplastic elastomer compound, consisting of: (a) from about 20 to about 35 weight percent of a polyphenylene ether, based on the total weight of the compound, wherein the polyphenylene ether is unblended or blended with an aromatic vinyl group thermoplastic resin; (b) from about 20 to about 40 weight percent of a hydrogenated styrenic block copolymer, based on the total weight of the compound; (c) from about 5 to about 30 weight percent of a combination of organo-phosphinate and melamine polyphosphate, based on the total weight of the compound; (d) from about 5 to about 30 weight percent of a nucleated olefinic polymer, based on the total weight of the compound; (e) from about 5 to about 30 weight percent of a plasticizing oil, based on the total weight of the compound; (f) from about 5 to about 25 weight percent of a tackifier, based on the total weight of the compound; and (g) optionally, from 0 to about 5 weight percent of at least one additive, based on the total weight of the compound, wherein the additive is selected from the group consisting of antioxidants; pigments, colorants or dyes; stabilizers; and ultraviolet light absorbers; wherein the compound has a before-aging tensile elongation of >200% and an after-aging tensile elongation residual of at least 75%, according to Underwriters' Laboratory test UL 62; and wherein the compound has a V-0 rating at 3 mm thickness, according to Underwriters' Laboratory test UL 94.
