FLAME-RETARDANT POLYCARBONATE-ABS MOLDING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polycarbonate-ABS composition having improved flame retardancy, tensile strength, yield stress, and tensile elastic modulus.

SOLUTION: This thermoplastic flame-retardant molding composition contains A. 40-99 pts.wt. of thermoplastic polycarbonate or polyester carbonate, B. 0.5-60 pts.wt. of graft polymer that contains B.1 5-95 wt.% of one or more vinyl monomers and B.2 95-5 wt.% of one or more graft bases having a glass transition temperature of <0°C and an average particle diameter (d50value) of 0.20-0.35 μm, C. 0-45 pts.wt. of thermoplastic vinyl copolymer, D. 0.5-20 pts.wt. of a mixture of phosphorus compounds, and E. 0.05-5 pts.wt. of fluorinated polyolefine.
