Abstract:
A flame retardant thermoplastic composition has high flame retardance at low thicknesses, good flow properties, good impact strength, and good flexural modulus. The polymer composition includes a polycarbonate polymer, a flame retardant additive, talc, glass fibers, and an acid stabilizer in synergistic amounts.

Claim (Index 1):
A flame retardant thermoplastic composition comprising:\n at least one polycarbonate polymer; at least 0.05 weight percent of a flame retardant additive; 2 wt % or more of glass fibers; 2 wt % of more of talc; and an acid stabilizer; wherein the weight ratio of the talc to the glass fibers is from 0.65 to 2, the composition contains 9 wt % to 12 wt % of the glass fibers and the talc combined, and the weight ratio of the acid stabilizer to the talc is from about 0.01 to about 0.05; wherein the thermoplastic composition has a melt volume rate of 10 to 25 cc/20 min when measured according to ISO 1133 at 300\u00b0 C. and a 1.2 kg load, a flexural modulus of at least 3.0 GPa when measured according to ISO 178, a Vicat B120 softening temperature of 135\u00b0 C. to 160\u00b0 C. when measured according to ISO 306, and a notched lzod impact strength of at least 60 J/m or greater when measured at room temperature per ASTM D256; wherein the flame retardant additive is potassium diphenylsulfon-3-sulfonate or a blend of potassium diphenylsulfon-3-sulfonate and sodium toluene sulfonate; and wherein an article molded from the thermoplastic composition can attain UL94 V0 performance at a thickness of 1.2 mm.
