Patent ID: 7884150

Claim:
A flame retardant composition, comprising: a styrenic block copolymer, wherein the styrenic block copolymer has at least one hard polymer block derived from at least an aromatic vinyl compound unit, and has at least one soft polymer block, wherein the soft polymer block includes at least one repeat unit derived from an olefin or a diene; a polyolefin polymer or copolymer in an amount from about 30 to about 210 parts based on 100 parts by weight of the styrenic block copolymer, wherein the polyolefin copolymer is a) a greater part by weight of one or more olefin monomers and a lesser amount of one or more non-olefin monomers or b) two or more different olefin monomers; a softener in an amount from about 10 to about 250 parts by weight per 100 parts by weight of the styrenic block copolymer; two or more flame retardants, including a halogenated flame retardant in an amount from about 10 to about 250 parts based on 100 total parts by weight of the polyolefin polymer or copolymer, styrenic block copolymer and softener; and a nanoparticulate comprising one or more of an organically modified clay and a nanoclay in an amount from about 0.5 to about 30 parts, based on 100 total parts by weight of the polyolefin polymer or copolymer, styrenic block copolymer and softener.
