Claim:
1. A heat resistant, flame retardant polylactic acid compound, consisting of: (a) from about 30 to about 39 weight percent, by weight of the compound, of polylactic acid; (b) a carbonate polymer selected from the group consisting of (c) a non-halogenated flame retardant selected from the group consisting of polyphosphates, phosphinates, polyphosphonates, phosphonates, phosphates, polyphosphonites, phosphonite salts, hypophosphite, hypophosphinite, phosphonite, phosphite, phosphorus oxide, phosphoramide, phosphoramidate, phosphorus nitrile, phospham, phosphoryl nitrile, phosphorus nitride amide, imidophosphazene, polyphosphazene, phosphazene, phosphorus oxynitride, organophosphates, red phosphorus, and combinations thereof; (d) a fluoropolymer drip suppressant; (e) optionally, an inorganic synergist selected from the group consisting of zinc borate, talc, and a combination of them; (f) optionally, a core/shell siloxane/(meth)acrylate copolymer impact modifier; (g) optionally, a oligomeric chain extender; and (h) optionally, one or more other additives selected from the group consisting of adhesion promoters; anti-fogging agents; anti-static agents; biocides; bonding, blowing and foaming agents; dispersants; initiators; lubricants; pigments, colorants and dyes; plasticizers; processing aids; release agents; slip and anti-blocking agents; stearates; ultraviolet light absorbers; viscosity regulators; waxes; and combinations of them; wherein the compound when molded into a plastic article has a UL 94 rating of V-0 when tested at a 3.2 mm thickness.
